I cannot seem to be able to make the following minimal example run:

cat <<EOF > demo.sh
#!/bin/sh

VAR="\$(< /dev/stdin)"
echo \$VAR
EOF

sudo chmod +x demo.sh
docker run -it --rm -p 8080:80 -v $(realpath demo.sh):/script beefsack/webify:latest

and then:

curl http://localhost:8080 -d $(date '+%Y-%m-%d')

Am I doing something wrong? Expected output is the current date. Actual is a blank line.
I would like to help with extending webify if this is a missing feature and I find the time.

When the client closes the connection, we see errors in the server stderr such as:

2020/08/29 21:09:56 error writing response body: write tcp [::1]:8080->[::1]:50044: write: broken pipe

These aren't useful errors and should be suppressed. These errors have the value syscall.EPIPE.

The examples in the README aren't useful. Implement a more realistic minimal example and update documentation to clarify what webify should and shouldn't be used for.

命令行下不方便，怎么展现到web上。
本来执行的代码：

进入pyspark

pyspark
sql='select * from table2'
spark.sql(sql).show()
我想实现的效果是，写一个python函数，传入不同的页面，在web上展示sql的结果。

You might put a word about security :-)
Like "Make sure your machine is not accessible from Internet when exposing shell commands".

is the project still active?

Hi,
I'm searching for a solution to replace a project i use : https://github.com/eoli3n/shellcast
It's a nodejs app, that I didn't maintain, but which works well.

It is kind of webify but with those features:

• Multiple instances in a declarative yaml file
• a Single webserver which map commands to routes. http://localhost/command1 http://localhost/command2
• dynamic commands with php args -> shell args
• password protection for each webservices
• plain output (curl) and JS realtime shell output
• realtime highlighter by word|line in JS output

I'm still looking for a tool to replace it. I need same features but i can skip the js realtime shell output part.
If i don't find anything, i will maybe upgrade shellcast and fix vulnerabilities.

I would like to webify a service for encrypting files (oversimplification, but let's just say they are short yaml files to be encrypted).
The way I envision interacting with webify is to curl it with:

• the key to be used in encryption (a separate file).
• the yaml to be encrypted.

Something like:

curl \
  -F "key=@/home/me/key" \
  -F "input_yaml=@/home/me/input.yaml" \
  localhost:8080

How do I store the key and input.yaml files on the backend side to start the process?

Add support for runtimes:

webify [--runtime=docker|azure|aws|gcloud|localhost] <command>

Running docker run -it -v script.sh:/script ... does not work unless:

1. Host is linux (binding a single file, not folder with -v does not seem to work on macOS)
2. Docker engine is running on the same machine where the docker run command is being executed (often not the case; I am on macOS and use docker-machine).

The idea is for this to be a stepping stone to building docker images that can run as Azure Functions or other "serverless" runtimes.

Also keeps webify pure in that --runtime can default to "localhost" (i.e. just run webify locally as now).

Runtime Docker

1. build docker image with script copied
2. either echo "image name" or docker run -it --rm <image> ?

Runtime Azure

No idea yet, but https://github.com/Azure-Samples/functions-custom-handlers/tree/master/go might be a starting point

Using webify in docker, I'm seeing cached values for simple text:

script.sh:

#!/bin/sh

echo foo

docker run -d --rm -p 8080:80 -v  $(realpath script.sh):/script beefsack/webify

If I change foo to bar, curl http://localhost:8080 still displays the old value.

This only occurs in Docker, if I run webify on baremetal, the updated value bar is displayed.

Really Nice , would be even better if it serves on websockets. Accepting user input on the fly. It will then become a true terminal in browser.

I like the idea that webify can quickly turning a cli command into a http service.
I wrote a ruby script to implement it with 6 lines of codes using pure ruby.
here is the gist: https://gist.github.com/rainchen/3a91ef481e78ad38d51c91da0ab40e7f
have fun~
