App Deployment

[danhunsaker]

• CLI tool performs the following steps:
  • look up the data warehouse service in the target app
  • upload or sync the deployable code under /app
  • upload or sync the contents of /data
  • register a new deploy with the Core
• Remove oldest deploy(s) until only the configured amount remain

The above steps are skipped if a redeploy is triggered from the user's dashboard.

• Process boxfile to determine what components to create/update
• Install latest images for each component on the server(s) it will be created on
• Create new containers for the new components (data components in the first pass, if applicable; code components in a second pass afterward)
• Configure new containers
  • Migrate data between data containers
  • Install deploy contents in code containers
  • Run transform hooks in code containers
  • Make /app and its contents read-only, except where marked writable
• Start new containers
• Run before_live hooks in new containers
• Redirect traffic to new containers
• Stop old containers
• Remove old containers
• Run after_live hooks in new containers
