Remote Rollback Command

Rollback the remote development environment to a previous Docker image version.

Commit SHA (optional): {{args}}

Workflow

1. Assess Current Situation

Get current problematic version:

ssh -i {SSH_KEY_PATH} {REMOTE_USER}@{REMOTE_HOST} "docker inspect {APP_CONTAINER} | grep 'org.opencontainers.image.revision' | cut -d'\"' -f4"

Check current status:

curl -s http://{REMOTE_HOST}:{DEV_PORT}/api/health 2>/dev/null || echo "Health check failed"

Document the issue for Linear ticket creation later.

2. List Available Rollback Targets

Show recent images on remote host:

ssh -i {SSH_KEY_PATH} {REMOTE_USER}@{REMOTE_HOST} "docker images {REGISTRY}/{IMAGE_NAME} --format 'table {{.Tag}}\t{{.ID}}\t{{.CreatedAt}}'"

Cross-reference with git commits to show messages:

!{git log origin/main -10 --oneline}

3. Select Rollback Target

If argument provided (commit SHA like e9722d4):

• Use specified commit as rollback target
• Verify image exists with that SHA tag

If no argument provided:

• Display last 5 available images with commit messages
• Recommend previous stable version (before current)
• Ask user to confirm selection

4. Pull Rollback Image

Pull the specific version from registry:

ssh -i {SSH_KEY_PATH} {REMOTE_USER}@{REMOTE_HOST} "docker pull {REGISTRY}/{IMAGE_NAME}:{TAG_PREFIX}-{target-sha}"

5. Update Configuration

Create backup of current config:

ssh -i {SSH_KEY_PATH} {REMOTE_USER}@{REMOTE_HOST} "cd {PROJECT_PATH} && cp {COMPOSE_FILE} {COMPOSE_FILE}.backup.$(date +%Y%m%d_%H%M%S)"

Update docker-compose file to use specific image tag.

6. Restart Services

Restart with rollback image:

ssh -i {SSH_KEY_PATH} {REMOTE_USER}@{REMOTE_HOST} "cd {PROJECT_PATH} && {DOCKER_SCRIPT} restart"

Monitor startup:

ssh -i {SSH_KEY_PATH} {REMOTE_USER}@{REMOTE_HOST} "cd {PROJECT_PATH} && {DOCKER_SCRIPT} logs --tail 50"
