Values File

Most packages will require some shared secrets. We recommend storing the values.yaml in an encrypted S3 bucket. Geodesic Overview makes this easy using the s3 command to mount S3 buckets to the local filesystem.

Mount secrets:

s3 mount

Installing Github Authorized Keys

Install Github Authorized Keys if you want to enable users to login to the cluster via SSH using their Github Usernames & Github SSH keys.

To install github-authorized-keys on all nodes (including master nodes), you can run the following commands.

NOTE: The Kops bastion is not part of the kubernetes cluster, thus DaemonSets cannot be deployed to this instance. One alternative is to deploy a bastion helm chart.

Simply run,

source /secrets/github
helm install --name ghk --namespace=kube-system \
  --set "githubAPIToken=${GITHUB_API_TOKEN}" \
  --set "githubOrganization=${GITHUB_ORGANIZATION}" \
  --set "githubTeam=${GITHUB_TEAM}" \
