deployd

Update Kubernetes deployments and Docker Swarm services using webhooks

Kubernetes

• Create a service account:
  kubectl create serviceaccount deployd
• Create a role binding allowing the service account to perform edits:
  kubectl apply -f role-binding.yaml
• Create a secret named deployd-secret with key token
• Create the deployment:
  kubectl apply -f deployment.yaml
• Create the service:
  kubectl apply -f service.yaml
• Create an ingress

Docker Swarm

• See docker-compose.yml
• Make sure to set environment variable DEPLOYD_TOKEN to a new secret

Updating deployments/services

Updates of deployments/services can be triggered using, e.g.

wget --content-on-error --header "Authorization: $DEPLOYD_TOKEN" -qO- \
    https://$DEPLOYD_HOST/update\?name\=$DEPLOYD_NAME\&image\=$DEPLOYD_IMAGE:$DEPLOYD_TAG

Here, $DEPLOYD_TOKEN is the secret token that was specified in the configuration, $DEPLOYD_NAME is the name of the service/deployment to be updated, $DEPLOYD_IMAGE is the name of the Docker image that should be used, and $DEPLOYD_TAG is the tag of the Docker image that should be used.
