kubicorn's Introduction

Create, manage, snapshot, and scale Kubernetes infrastructure in the public cloud.

Phonetic pronunciation: KEW - BHIK - OH - AR - IN

Project Update

Kubicorn will be going through a breaking API change as we adopt the upstream cluster API
Kubicorn has moved to github.com/kubicorn/kubicorn permanently.
Kubicorn will be targeting a stable release shortly!

About

kubicorn is a free and open source project that solves the Kubernetes infrastructure problem and gives users a rich golang library to work with infrastructure.

kubicorn is a project that helps a user manage cloud infrastructure for Kubernetes. With kubicorn a user can declaratively create new clusters, modify and scale them.

NOTE: This is a work-in-progress, we do not consider it production ready. Use at your own risk and if you're as excited about it as we are, maybe you want to join us on the #kubicorn channel in the Kubernetes Slack community.

Previously, we mainly used a channel in the Gophers Slack community, which is still active, but we're moving to the Kubernetes Slack. You can also get involved and send your questions to our public mailing list.

We hold developer calls biweekly on Tuesdays, 1pm Pacific Time. By joining the mailing list, you'll get a calendar invite.

Proudly packaged with Golang dep

Core Values

Community first.

This is a community driven project. We love you, and respect you. We are here to help you learn, help you grow, and help you succeed. If you have an idea, please share it.

Developer empathy.

We are all software engineers, and we all work in many different code bases. We want the code to be stable, and approachable. We strive for clean and simple software, and we encourage refactoring and fixing technical debt.

Operational empathy.

We want our tool to work, and work well. If an operator is running kubicorn it should feel comfortable and make sense to them. We want operators to feel empowered.

Infrastructure as software.

We believe that the oh-so important layer of infrastructure should be represented as software (not as code!). We hope that our project demonstrates this idea, so the community can begin thinking in the way of the new paradigm.

Rainbows and Unicorns

We believe that sharing is important, and encouraging our peers is even more important. Part of contributing to kubicorn means respecting, encouraging, and welcoming others to the project.

Installing

$ go get github.com/kubicorn/kubicorn

..or read the Install Guide.

Quickstart

This asciicast shows how to get a Kubernetes cluster on DigitalOcean using kubicorn in less than 5 minutes:

Concepts

Create

kubicorn lets a user create a Kubernetes cluster in a cloud of their choice.

Apply

Define what you want, then apply it. That simple.

Scale

kubicorn is powered by a state enforcement pattern. A user defines the intended state of Kubernetes infrastructure, and kubicorn can enforce the intended state.

Enforce

kubicorn is built as a library and a framework. Thus allowing it to be easily vendored into operator and controller patterns to enforce intended state of infrastructure.

kubicorn's Issues

install fails with `undefined: bootstrap.Asset`

When I try to install I get an error about bootstap.Asset being undefined. I believe its looking for a function inside the bootstrap.go file that was removed here - #21

$ go get github.com/kris-nova/kubicorn
# github.com/kris-nova/kubicorn/cloud/amazon/resources
../go/src/github.com/kris-nova/kubicorn/cloud/amazon/resources/launchconfiguration.go:165: undefined: bootstrap.Asset

Hook up Issues to Twitter

We have https://twitter.com/kubicornk8s can we please connect our issues to twitter account so we can see and show off what is being open/closed?

Need to copy the kube_config down to workstation

Build a more reliable testing infrastructure?

It seems that the travis CI is just a make test, I don't think it will be good enough if more PR will be coming this way. Thus, to build a reliable testing infrastructure seem to be on the critical path. Thoughts?

We need IDs out of the API

Having IDs in the API is going to kill us moving forward. They were there at first to help with our POC, but we need them gone gone gone.

I can provide more information if anyone wants to take this.

Add Volumes

We need to add volumes definition to the API, and add it to any existing implementations

Test Harness

We need to flesh out a test harness for the following

Integration tests
Unit tests

I have a credit card, and am happy to share if anyone wants to take this and set up testing accounts anywhere.

Will need make targets
Will need an example test or two that demonstrate how the harness works
Will need to add documentation on how to use the harness

Github Pages

We need someone to build out the framework for github pages for

kubicorn.com
kubicorn.io

Sam says use semver!

We need to make sure we uphold semver for dep

Generate token for kubeadm

Right now we hard code a token, this is horrible. We need to auto generate one.

Contributing file

We need to document the contributing process

Implement Openstack

Hey,
Unfortunately I don't have access to EC2 or Azure, it is possible to create some sort of profile for Openstack environment? If so I would be happy to help (I work on openstack a lot)

Can we make our github labels rainbow?

Can someone who has opinions and can see color help me change the labels to a rainbow color theme?

Please add additional instruction to build kubicorn from source

Have added a short instruction for newbies to build kubicorn from source:
https://github.com/kubernauts/kubicorn/blob/master/docs/walkthrough.md

This part is new after the line:
$ go get github.com/kris-nova/kubicorn:

If you're new to Go, before you proceed you've to set GOPATH and build the kubicorn binary from source. For this you'd need to build go-bindata and provide it in your path:

Set GOPATH in your bash profile:

$ vi .bash_profil
export GOPATH=/Users/<your user>/go
export PATH=$GOPATH/bin:$PATH

$ go get github.com/jteeuwen/go-bindata
$ cd $GOPATH/src/github.com/jteeuwen/go-bindata/go-bindata
$ go build
$ cp go-bindata /usr/local/bin/

And run make from the src directory of kubicorn:

$ cd $GOPATH/src/github.com/kris-nova/kubicorn/
$ make

The kubicorn binary will get built and placed under $GOPATH/bin, run kubicorn -h to get the nice Unicorn:

$ kubicorn -h

The next thing

Please add it to the official walkthrough:
https://github.com/kris-nova/kubicorn/blob/master/docs/aws/walkthrough.md

Thanks kindly!

We need our API refactored

So one of the main goals of the project is to ultimately consume a community standard API that will work with Google!

The API is a work in progress that will live here: https://github.com/kris-nova/cluter-api

Furthermore, we need someone to audit and review this API, as it will be a good candidate for a starting point for the cluster API project.

I kind of hate the words we use now to represent things, can we please change them? I am terrible at naming things.

Kubernetes Version

This is a big one - we will need to start versioning our releases to support different k8s versions

Commands should provide some context on execution

Currently, when running for example kubicorn create the execution by default is silent. This is not a good UX, new users might think nothing happened. So after execution, the command should output a summary and suggest next steps, for example:

$ kubicorn create --name myfirstk8s --profile aws
I've created _state/myfirstk8s/cluster.yaml based on your input and now you can run kubicorn apply

E2E testing harness

We need to build an e2e suite that we can run to verify kubicorn is working. We can run this before a release and actually create/destroy clusters.

Again, I have a credit card if you want to hook shit up to the cloud.

Cheers!

Build in support for snapshots

Glossary

Snapshot: The process of creating an image
Image: The artifact created from taking a snapshot

We need to implement and flesh out the kubicorn snapshot command.
We need to delete the kubicorn image command

What is a snapshot?

A tarball.

A tarball that holds all relevant data to rebuild a Kubernetes cluster (both infra and app).

How do we make one?

We dump all the yaml into a directory and compress that shit up.

No seriously, that is what we do.
We need to pull the kubicorn cluster api into the directory, as well as all the yaml from kubectl

How do we apply one?

We do the reverse of the above.

Things you will need to do

vendor kubectl
write something that dumps all the yaml to disk
write something that will compress/decompress the directory into a tarball
verify you can create a cluster, then create some apps, then create and image
nuke your cluster
apply your newly created image
verify it's the same
win

API machinery improvements

Right now we are vendoring in API Machinery (good) but we aren't really using it all that well (bad)

Can we tidy up our API Machinery implementation and make it awesome?

Installing documentation

We need docs on how to build/install/download this thing

Bypass password auth for SSH keys by global env var

We need to have an optional environmental variable to disable ALL password interactive auth (for our friends in CI/CD land)

Success Criteria

The environmental variable is documented, and follows the standard KUBICORN_ prefix. (You can see examples in any of the cobra commands)
The environmental variable is always called using os.Getenv and never cached
Please define the new variable here https://github.com/kris-nova/kubicorn/blob/master/docs/envar.md

I believe this is related to: krisnova/klone#13

We need a file parser

We need a package/tool/etc that takes a string

myString string

and attempts to turn it into another string

myString string

with the caveat being that we need the first string to represent some type of file resource, and the second string to represent it's content.

Examples:

~/data -> content
/tmp/data -> content
http://nivenly.com/data -> content
https://nivenly.com/data -> content
s3://something/data -> content

Azure implementation

We need azure :)

Signal Handler Interface

We need to create a global signal handler, that will reference an interface. Each reconciler should implement said interface so that we can handle POSIX signals globally.

If you are interested in coding we should talk, because I would want to hear your ideas! Otherwise I might just code this.

Clean up API object

We need to add the json:"" camelCase to the members, also omitonly most of them

Also we need to see which members we are/aren't using and remove any unused members

Delete should update API

Right now when we delete a cluster, we don't update the state

Signal handler and support for AWS

and try to die nicely instead of aborting

Nodes need token and bootstrapping

We need to help the nodes join the master by pre generating the kubeadm token and passing it to both the masters and the nodes.

New user on-boarding

It would be great to have a walkthrough supporting new users how to do the basic steps

Cluster name in kubeconfig should reflect cluster name

Looks like right now the cluster name in kubeconfig is hard coded to kubernetes. Should probably use the cluster name used in the state store.

Kubicorn Logo

Who has mad art skills and likes to draw unicorns? Or maybe unicorns with gophers? Or maybe a gopher unicorn? gophercorn? kubigoph?

Ideally something we could put on the README.md and also render into ascii to replace the existing unicorn.

Force overwrite state store

When doing a create in a directory where the state store already exists, the tool barks and stops:

$ kubicorn create --name myfirstk8s --profile aws
2017-07-15T16:17:11-06:00 [✖]  State store [myfirstk8s] exists, will not overwrite

The user at this moment does not have enough information to know how to overcome the situation, for example by removing the state store like so: rm -R ./_state/myfirstk8s/.

Bootstrap script at runtime

Right now build the bootstrap shell scripts into the binary (debatably a bad idea).
We need a way to add the following types to the bootstrap script directive in the cluster API.

The bootstrap scripts are defined here https://github.com/kris-nova/kubicorn/blob/master/profiles/simpleamazon.go#L33

and need to support the following

local disk
http/https resources

Implement CI/CD Testing

I have a credit card, if you have skills and opinions!

Goal

run make test for every PR and only allow merging on exit 0

SCP Package

Okay so we use SSH to copy files in the kubeconfig package https://github.com/kris-nova/kubicorn/blob/master/cutil/kubeconfig/kubeconfig.go

...and we just added support for using an SSH agent #102

.... and we will need to scp files in the digital ocean pull request #35

.......... which is making me think we just need to crack down and get an scp package in the code base

I know that the teleport project has something similiar https://github.com/gravitational/teleport/blob/master/lib/sshutils/scp/scp.go

So we either need to write something ourselves, or we need to vendor in something, but we need a good reliable way of executing ssh and scp commands easily for ad-hoc reasons in the code base.

So part of this ticket involves defining the new way of doing things, and porting over the kubeconfig package to using the new world order.

Once this is done, we can wrap up the digital ocean PR

Should be able to kubicorn list

Should return the list of available states.

Apache 2 License Headers

In order for us to be truly Apache 2 compliant we need headers on top of all source code files

So can we please build out support for the following:

make headers that will run an idempotent "fix" for all files in the repository (sans vendor).
make check-headers that will run a check to validate all files have correct license headers. We will eventually want this to be called from make test and fail if a license has the wrong or missing header.

Every header should reference The Kubicorn Authors which is the /AUTHORS file that is automatically generated every release

Autocomplete state names

Should be able to tab complete the state names from the list of states in _state using bash/zsh completion

Digital Ocean implementation

Peeps want DO :)
