helm-runner

Docker image with helm and kubectl command-line tool.

Environment Variables

BITBUCKET_PROJECT_CLONE_URL

Helm charts are stored in separate project (bln-cluster-kube). We need to clone this project into our docker image to run helm command. This value is base64 encoded.

echo "BITBUCKET_PROJECT_CLONE_URL"| base64 | pbcopy

CLUSTER_CONTEXT

We have few clusters on AWS. We need to specify which cluster Tiller is going to talk to helm client.

HELM_COMMAND

This is the command we are running.

KUBECTL_CONFIG

This is Cluster configuration file from ~/.kube/config . Helm needs configuration file to connect kubernetes cluster. configuration file is taring and base64 encoding as bellow.

cat $HOME/.kube/config | gzip | base64 | pbcopy

Codeship Usage

BITBUCKET_PROJECT_CLONE_URL and KUBECTL_CONFIG

Append the encoded environment variable value to the environment variable name with =. For an example KUBECTL_CONFIG=BASE64_ENCODED_VALUE_SEE_INSTRUCTIONS_ABOVE. Copy the whole key value pair as a string and use the following to encrypt it.

pbpaste > raw.tmp && jet encrypt raw.tmp crypt.tmp && cat crypt.tmp | pbcopy && rm raw.tmp crypt.tmp

The value can now be added an array item to a encrypted_environment in codeship-services.yml.

HELM_COMMAND and KUBECTL_CONFIG

Add values as array of environment variables in codeship-services.yml.
