uwsgi-nginx-flask-docker's Introduction

Hey! I'm @tiangolo (Sebastián Ramírez) 👋

I'm a software developer from Colombia. 🇨🇴

I currently live in Berlin, Germany. 🇩🇪

I have been building APIs and tools for Machine Learning and data systems, in Latin America, the Middle East, and now Europe, with different teams and organizations. 🌎

I created FastAPI, Typer and a bunch of other open source tools. 🚀

I like to build things with Deep Learning/Machine Learning, distributed systems, SQL and NoSQL databases, Docker, Python, TypeScript (and JavaScript), modern backend APIs, and modern frontend frameworks. 🤖

I'm currently dedicating a high percentage of my time to FastAPI, Typer, and my other open source projects. At the same time, I'm also helping a limited number of teams and organizations as an external consultant. If you would like to have my help with your team and product, feel free to contact me. 🤓

If my open source projects are useful for your product/company you can also sponsor my work on them. ☕

uwsgi-nginx-flask-docker's Issues

Unable to change nginx.conf in the image

This may seem a little strange, but I am not able to change nginx.conf file inside /etc/nginx/conf.d/nginx.conf

Here is what I did:

Method1: Change in Dockerfile

My Dockerfile looks like this:

FROM tiangolo/uwsgi-nginx-flask:flask
COPY ./app /app
COPY ./changes/nginx.conf /etc/nginx/conf.d/nginx.conf
COPY ./changes/nginx.conf /app/

./changes/nginx.conf looks like this:

server {
    location /app1/ {
        try_files $uri @app;
    }
    location @app {
        include uwsgi_params;
        uwsgi_pass unix:///tmp/uwsgi.sock;
    }
    location /static {
        alias /app/static;
    }
}

Note the change in location in above server block from location / to location /app1/

After the image is built and I run the docker container, I exec into the running container
sudo docker exec -ti CONTAINER_ID /bin/bash

cat /app/nginx.conf shows presence of updated nginx.conf file (location changes from / to /app1/

BUT cat /etc/nginx/conf.d/nginx.conf still shows the old conf file (location is still /)
I thought maybe the second COPY line is not getting executed successfully and docker isn't throwing error on console (sudo?). So, I changed the conf file manually and did a docker commit - the second approach mentioned below.

Method2: Docker commit

After the docker container was up and running, I used exec to login into the container using
[vagrant@localhost]$ sudo docker exec -ti CONTAINER_ID /bin/bash

[root@CONTAINER_ID]# vi /etc/nginx/conf.d/nginx.conf
Changing the file to reflect below:

server {
    location /app1/ {
        try_files $uri @app;
    }
    location @app {
        include uwsgi_params;
        uwsgi_pass unix:///tmp/uwsgi.sock;
    }
    location /static {
        alias /app/static;
    }
}

Saved the file wq! and exit the container.
After that I did sudo docker commit CONTAINER_ID my_new_image

Starting a new container and re-logging into container running on my_new_image still gives below nginx.conf file inside /etc/nginx/conf.d/nginx.conf:

server {
    location / {
        try_files $uri @app;
    }
    location @app {
        include uwsgi_params;
        uwsgi_pass unix:///tmp/uwsgi.sock;
    }
    location /static {
        alias /app/static;
    }
}

I can tell that the my_new_image has some changes because it is larger in size than tiangolo/uwsgi-nginx-flask-docker because I had installed vim to edit the file. But somehow file changes are not persisting inside /etc/nginx/conf.d/nginx.conf.

Am I doing something wrong or is it some bug?

can't send email in flask docker

our smtp server use port 25 as mail server , but we can not send email in our container.

Changing `WORKDIR` causes uWSGI to not find app

I have a Dockerfile with the following contents:

FROM tiangolo/uwsgi-nginx-flask:python3.6
COPY app /app
COPY foo /tmp/foo
WORKDIR /tmp/foo
RUN some other commands
# More RUN commands

When I build this image I get the following errors:

ModuleNotFoundError: No module named 'main'
unable to load app 0 (mountpoint='') (callable not found or import error)

Why does the WORKDIR in my Dockerfile affect the functionality of the base image?

My apologies if this is obvious or expected behaviour; I don't have much Docker experience.

Invalid checksum for python3.6

Looks like the checksum is invalid for one of the layers in python3.6 causing pull failure:

How to config the context path

Is there any way to config the app to run at
http://url/my_custom_path

instead of at the root?

Cannot install module lxml.

at alpine cannot install module lxml like : pip install lxml,
but i find packages py3-lxml, i can install module like : apk add py3-lxml,
it used for my alpine linux or my dockerfile(form alpine:3.7)

`FROM tiangolo/uwsgi-nginx-flask:python3.6-alpine3.7
#FROM alpine:3.7

RUN apk update add python3
RUN apk add py3-lxml
RUN pip3 install pip==10.0.0
RUN pip3 freeze
`
if i use base from alpine:3.7,lxml be install,
use you tiangolo/uwsgi-nginx-flask:python3.6-alpine3.7,lxml be not install.

some bug?or?

Add prefix to flask application URLs

I am wondering if you would consider allow users of this docker image to be able to set their own prefix of the flask application. For example, I would like to do something like this:

location \ served directly from a directory, not just index.html
location \api served by flask app

Or better yet, allow users to use their own nginx.conf. We could do this by checking if a nginx.conf file already exists before generating one in entrypoint.sh.

Thanks!

add pip to container

how to add pip to container? I mean sure, can do con command but doesn't it change the behaviour?

Passing arguments to main.py

I'm trying to understand how the main.py file in the /app folder is called, and how I can send arguments to it? I have a project where I would like to start the main.py file by passing it an argument when I create a container.

ggc breaks nginx?

I am trying to use tiangolo/uwsgi-nginx-flask:python3.6 as a base image so that I can build a Docker for my Flask WebApp. I have a Kerberos and MS SQL Server dependency. I have been racking my brain trying to get this to work for awhile. I think the problem is with gcc. I couldn't figure out what was wrong for a while and finally just started off adding one program at a time. I didn't get too far till I got the error below.

Python 3 version

Could you provide a 3.5 python image?

Python packages still not available to app after pip install

I have additional requirements I need to install for my app. Here's my Dockerfile:

FROM tiangolo/uwsgi-nginx-flask:python3.6

ENV STATIC_INDEX 1

COPY requirements.txt /app/
RUN pip install -r /app/requirements.txt

COPY . /app

Even after rebuilding, the app still can't import my packages. When I bring up the docker container, I get this in the output:

Traceback (most recent call last):
  File "./main.py", line 4, in <module>
    from flask_cors import CORS

The build step does show it installing the package.

Using SSL Certificates

Hi Tiangolo! Thank you for this.

I'm having a real hard time installing SSL certificates for this docker image.

Is there any additional changes I should implement?

This is how I have modified nginx.conf:

server {
    listen 80 default_server;
    listen [::]:80 default_server;

    # Redirect all HTTP requests to HTTPS with a 301 Moved Permanently response.
    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;

    # certs sent to the client in SERVER HELLO are concatenated in ssl_certificate
    ssl_certificate /etc/ssl/www.messiac.com.crt;

No support for HTTPs

I'm trying to figure this out now. I would prefer not to check the keys into my repo or bake them into the image.

As it stands, it looks like I'll have to overwrite entrypoint.sh so that it writes a different nginx.conf that points to a cert and a key in a volume that runner of the container can create. I'm pretty new to docker though... any recommendations?

Do I still need supervisor if I use this setup?

Do I still need supervisor if I use this setuup?

Logging problems

Hi tiangolo,

I am having problems logging messages when I used the uwsgi-nginx-flask image. The application works. I am only having issues with the logging. On the other hand, If I run the app in standalone, everything, including logging, works as expected.

I tried to look for info on how to configure the logging mechanism when using uwsgi-nginx-flask, but I was not able to find anything.

Let me explain the scenario.

I am using uwsgi-nginx-flask:python3.6 to run a flask app.

My uwsgi.ini is

[uwsgi]
module = iedapp.app
callable = app
logger = python

The app is using resources for handling request.

....
app = Flask(__name__, static_folder=None)
app.config.from_object(config)
api = Api(app, prefix='/api', base_path='/api', api_version='1.0')
api.add_resource(IedOnline, '/online/<string:ied_key>/<string:layout>')
....

And in the resource, I have something like

....
logger = logging.getLogger('test')

class IedOnline(Resource):
    def post(self, ied_key, layout):
         print("Hello!!!")
         current_app.logger.error("Hello again!!!!")
         logger.error("Hello again and again")
....

What happens to me is that both the print and logging messages in the resource function get lost. I am not able to find them either in the docker logs not if I exec into the docker image and look for entries in all the *.log files in the image.

Could you provide guidance on what I should be going wrong?

NGINX don´t start

Hi, sorry for my noob question, but i´m beggining on docker.

Is It there something that disable nginx when I start a container with debug directives ? I started the container using this command line:

docker run -d --name mycontainer -p 80:80 -v $(pwd)/app:/app -e FLASK_APP=main.py -e FLASK_DEBUG=1 myimage flask run --host=0.0.0.0 --port=80

After do some packages instalations on container I commited to a new image. After this, when I start a new container using this new image, it always run in debug mode.

net::ERR_INCOMPLETE_CHUNKED_ENCODING

I have a jquery front end that is trying to send images to an app inside the uwsgi-nginx-flask-docker container.

The javascript console is saying this:
jquery.min.js:4 POST http://localhost:8000/predict/ net::ERR_INCOMPLETE_CHUNKED_ENCODING

If I use the same app with only gunicorn it works ok, so I'm suspecting this is related to nginix configuration inside the container?

Adding own domain and SSL certificates

Hi,

first of all thank you very much for this image. It has made everything so much easiert. I don't know if that belongs here but could you give me a short description of how I can add SSL certificates and how I can use my own domain? Currently I just access the Flask app by opening the IP adress of my Ubuntu server.

Thanks a lot for your time.

Add ELK Elasticsearch to this template

Struggeling to find a good setup with ELK to monitor a flask api backend. I want to log all api requests and maybe certain things within the flask app. Would be awesome if this could be included here!

Environment variable NGINX_WORKER_PROCESSES not implemented

Documentation says NGINX_WORKER_PROCESSES can be configured, but it appears it is not actually implemented in uwsgi-nginx-flask-docker. I think you have to merge the following commit (from uwsgi-nginx-docker) with this repo as well.

As you can see, the restart script does not seems to get executed on the linux server. The docker on both machine has been updated to the latest version.

Would I be able to use any flask app, just making sure I have the main.py and everything in the app directory?

Or is there something different if I have static content (js, css, img) and templates (html)

[Question] Redirect loop

I want to redirect all www to non-www.
I have this in my custom.conf file :

server {
        server_name www.domain.com;
        return 301 $scheme://domain.com$request_uri;
}

But i receive a redirect loop. Do you have any idea why is that?
I am using the container with nginx-proxy
I think the issue happens beacuse there is double nginx-configuration.
One of nginx-proxy layer, second on uwsgi-nginx-flask-docker layer.

Isn't it better to just use pure uwsgi with nginx-proxy?

Cannot find Python module with Conda

Hi,
First of all, thanks for the great work!
I adapted the image by installing conda on top of it. I need conda to install the fast.ai library and all its dependencies. I do this on the base conda env.

When i try to run the container, it cannot find the fastai library.
However, when i run the container interactively, it runs the flask app without any issues. hence the Flask development webserver can find the fastai library but nginx/uwsgi/supervisor cannot.

Any idea how to solve this issue? What files / settings need to be adapted?

Thanks!
Francis

Connect postgres(psycopg2) with the main.py

I tried to connect postgres db from main.py, but its giving OperationalError: received invalid response to SSL negotiation: H. This issue is because the port 5432 is not properly exposed.

ENV LISTEN_PORT 5432

@app.route("/")
def hello():
    db = psycopg2.connect(host='127.0.0.1', port=5432, user='postgres',
                          password='123', dbname='chatbotdev')
    return "Hello World from Flask"

        include uwsgi_params;
        uwsgi_pass unix:/tmp/uwsgi.sock;
    }
}

requirements.txt
psycopg2==2.7.3.1

Can someone please explain, how can I use postgres within this docker container, because I'm able to do this in other linux docker containers.

Cannot update server block in nginx.conf

Due to the way that the external nginx configs are included into the root nginx.conf file, it's not possible to change the primary server block, which is something I need.

As a work around, we manually update the file to include various lines, but this isn't clean and it would be nicer to just put nginx configs into a folder somewhere and have them included automatically.

Alpine Linux

Have you considered using alpine linux?

ssl integration

I'm looking for a way to smoothly integrate ssl certificates through nginx config.
Any clues will be appreciated.

Connection aborted when accessing a HTTPS source

Hi,

using this image allowed me to properly start my app. However it kept failing at a certain point. I figured out that there is a problem at accessing an HTTPS source.

I isolated the respective part of my app and started it in a container. I basically just downloads a file from an S3 resource when I get the following error:

botocore.vendored.requests.exceptions.ConnectionError: ('Connection aborted.', RemoteDisconnected('Remote end closed connection without response',))

However starting the flask app locally with cmd on my Windows it works perfectly fine. I also tried it on a regular Apache2 server and got the same issue so I think it has to do something with uwsgi or the reverse proxy. In the flask code below you can see that I use a custom endpoint for S3 and not the service on AWS and this server is served with SSL. Could that be an issue? Can I solve this problem by changing the configuration on this image? Thank you very much.

app = Flask(__name__)

@app.route('/', methods=['GET', 'POST'])
def index():
    conn = boto3.client('s3', region_name="eu-west-1", endpoint_url="https://endpoint", aws_access_key_id=accesskey, aws_secret_access_key=secretkey)
    conn.download_file('mytestbucket22', 'aggregated.csv', 'aggregated.csv')
    return 'ok'

if __name__ == '__main__':
	app.run(host='0.0.0.0', debug=True)

Is not exiting gracefully

Using compose, after docker-compose up.
I ask it to quit,ctrl+C when started without detaching,
or else docker-compose down.
I noticed, that my flask-docker instance always time outs after the 10 seconds.

I believe that could be some issue with the pid-1-zombie-process thing.

Some references:

Can that issue apply here?

cannot use custom uwsgi.ini in flask app

Hi tiangolo!

I've been working around with your docker image to deploy my python application.
Things were fine until I tried customizing uwsgi.ini file.

First of all, following is my flask project architecture.

Inside my Dockerfile includes following lines.

FROM tiangolo/uwsgi-nginx-flask:python3.6
COPY ./app /app
COPY ./app/conf/nginx.conf /etc/nginx/
COPY ./uwsgi.ini /app/uwsgi.ini
COPY ./requirements.txt /app/
RUN pip install -r /app/requirements.txt
ENV UWSGI_INI /app/uwsgi.ini

and I also tried with following Dockerfile.

FROM tiangolo/uwsgi-nginx-flask:python3.6
COPY ./app /app
COPY ./app/conf/nginx.conf /etc/nginx/
COPY ./uwsgi.ini /app/uwsgi.ini
COPY ./requirements.txt /app/
RUN pip install -r /app/requirements.txt
ENV UWSGI_INI /app/uwsgi.ini
WORKDIR /app

My custom uwsgi.ini is as follows.

[uwsgi]
module = main
callable = app
lazy-apps = true
processes = 1

If I run a docker container with above image, I see following logs.

Thanks in advance!

Add additional Alpine base image for Python 2.7

Add Alpine base image for Python 2.7

Some users are fans of Alpine Linux, so it would be nice to have an additional base image based on Alpine.

This would depend on: tiangolo/uwsgi-nginx-docker#10 being solved first.

How to get the container's logs?

Hi tiangolo

Great thanks for your dockers, I could setup a simple web app with flask.
I found when the app kept running somethings, it will hang up.
When I connect the running container's bash, I could only get the flask logs on the bash.
But could not get the nginx logging.

Do you have any advice for it?
Thank you

running more than 2 processes

Hi,

Thanks for the great work. I've tried specifying the number of processes in uwsgi.ini, however it still defaults to 2. How do I spawn more than 2 processes?

Using root as user

Why do you not change user? Is it secure to run uWSGI with root privileges?

<title>500 Internal Server Error</title>

Internal Server Error

The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

How could I fixed the dockerfile setting?

Yesterday, I build a new dockerfile with my python project as usual. But when I start it up, the static files all broken down.

After some time debugging I found the static file path is not config as usual.

I use the COPY in dockerfile building to change the nginx static file path.
But now it did not working.
I try some other ways, it was still not working too.

Suddenly, I realize that maybe there is some thing wrong in the entrypoint.sh

Aha, you have change the static file config to ENV in docker file.

So I fix it following the instruction.

But I am worry about that if it will change some way sometimes in the future.

So my question is how could I get a fixed dockerfile settings but not auto update with the repository?

Thank you.

What is the last line in the Dockerfile

Im a little confused on whether the last line in my dockerfil be this:

CMD ["python", "main.py"]

Or should it be something else?

Too many “SIGPIPE: writing to a closed pipe/socket/fd” error for every seconds, on Flask + Nginx

Things work pretty OK for few hours, till my CPU suddenly spike up.

I even shutdown the node.js app, to ensure no one is sending POST to /stock_price_alert

Still, after I shutdown my node.js, Flask still keep generating the error log, and the CPU usage still very high.

May I know is there any other thing I can debug?

p/s Here's my docker stats output

Cannot load submodule

I have a project with structure below:

- /
  |- src
    |- main.py
    |- __init__.py
    |- submodule
      |- __init__.py
      |- ... 
    |- web
      |- web.py
      |- __init__.py
  |- Dockerfile

main.py calls entry function defined in web.py, and web.py calls functions defined in submodule. It works fine with command line python main.py. Then I plan to deploy it under docker, with Dockerfile:

FROM tiangolo/uwsgi-nginx-flask:python3.6
COPY ./src/* /app/

Build and run, I got error:

Traceback (most recent call last):
  File "./main.py", line 1, in <module>
    from web import run
  File "./web.py", line 5, in <module>
    import submodule
ModuleNotFoundError: No module named 'submodule'

Why did uwsgi cannot find submodule? Did I miss something?

Include libmysqlclient-dev

Many / most applications need a database. Can you add these dependencies, or show how you would recommend we add them ourselves?

Default uwsgi.ini overrides settings in the custom configuration

Hi, first of all, thank you for your great work!

I found a problem while deploying my app, which has a custom uwsgi.ini inside the app folder, on top of this docker image.
I want to set a different value for cheaper, but while changing all other cheaper-related settings (cheaper-initial, cheaper-step) works, settings cheaper=5 doesn't because the default uwsgi.ini (/etc/uwsgi/uwsgi.ini) sets cheaper = 2.

I validated this issue by overriding /etc/uwsgi/uwsgi.ini with my custom settings.
I guess the same will happen by trying to set processes (which is also declared in the deault uwsgi.ini) to a value different from 16.

I would be happy to create a PR fixing this issue, but I need some guidance on the way it merges the 2 configs (default and the custom one in /app) 🙂

COPY failed on step 9

When I use https://github.com/tiangolo/uwsgi-nginx-flask-docker/blob/master/python3.6/Dockerfile

It raise
Step 9/17 : COPY ./app /app
COPY failed: stat /var/lib/docker/tmp/docker-builder416121774/app: no such file or directory

i see the problem is from DBconfig import DB, Carriage, Carriage_plan, Train_plan。
but the DBconfig is my file . set some thing about SQLAlchemy

I think you can understand the problem。

now i try this:

it work out mydatabase.
