Auto Deploy

What Am I?

A script/go server that can receive webhooks from CI services (currently only Travis) and build docker images from the repo to deploy into Kubernetes using envsubst (not Helm)

What Do I Need?

1. To host this somewhere in your infra that has access to the following:

   • Your Git repos
   • Your Docker registry configured in the shell
   • Your K8S instance (with kubectl configured)

2. A webhook configured in your CI system

3. A deploy folder in your repo with files that match your branch names. i.e. deploy/master.deploy

How Do I Run It

go run autodeploy.go

What Can It Do?

1. Pull latest changes from git (based on branch tested)
2. Build docker image and tag with commit hash and branch name
3. Push docker image to your registry
4. Create a deployment file for k8s and auto set up ingresses (certificates must be set up by you, see env-deploy.yaml)
5. Deploy to K8S and save output of file to ran folder
6. Notify webhook of success and failures

Troubleshooting

Git fails with SSH_AUTH_SOCK

This is probably because your shell cannot find the ssh-agent or the path to the socket file is wrong.

To Fix

$ eval `ssh-agent`
$ ssh-add

Docker fails to build

Probably you need to add your user to the Docker group or, and this is NOT recommended, you can run as sudo

Docker fails to push to a registry

First, make sure you have a registry set and then make sure your auth credentials have been provided with:

$ docker login <REGISTRY>

TODO

• Handle args for config paths
• Allow selection of default build steps
• Git - handle initialising submodules
• Git - fetch branches before searching
• Docker - Print errors to users when command fails
• Config - enable or disable stdout
• K8S - create env file and pass to deploy
• Webhook - Notification of stages
• Better error handling and detection, no silent failures
