How to migrate from deploying via Docker Image to deploying via Git

Guide for migrating from deploying via Docker Image to deploying via Git

Overview

Suppose you configured your app to deploy via Docker Image, i.e., you deployed using aptible deploy in the past, and you want to switch to deploying via Git instead. In that case, you will need to take the following steps:

Step 1: Push your git repository to a temporary branch. This action will not trigger a deploy, but we'll use it in just a moment:

BRANCH="deploy-$(date "+%s")"
git push aptible "master:$BRANCH"

Step 2: Deploy the temporary branch (using the --git-commitish argument), and use an empty string for the --docker-image argument to disable deploying via Docker Image.

aptible deploy --app "$APP_HANDLE" \
        --git-commitish "$BRANCH" \
        --docker-image ""

Step 3: Use git push aptible master for all deploys moving forward.

Please note if your app has Private Registry Credentials, Aptible will attempt to log in using these credentials. Unless the app uses a private base image in its Dockerfile, these credentials should not be necessary. To prevent private registry authentication, unset the credentials when deploying:

aptible deploy --app "$APP_HANDLE" \
        --git-commitish "$BRANCH" \
        --docker-image "" \
        --private-registry-username "" \
        --private-registry-password ""

Congratulations! You are now set to deploy via Git.
