Cloud deployment process

The deployment process begins when you perform a merge, push, or synchronization of your environment, or when you trigger a manual redeployment. The deployment process takes time, but there are ways to optimize deployment that depend on whether you are developing and testing or working with a live site. Most notably, you can control the static content deployment.

There are three, distinct phases of the deployment process: build, deploy, and post-deploy. Each phase performs specific actions with limited resources:

Build phase Build phase

The build phase assembles containers for the services defined in the configuration files, installs dependencies based on the composer.lock file, and runs the build hooks defined in the file. Without the ability to connect to any services or access the database, the build phase depends on the resources limited to the environment.

Deploy phase Deploy phase

The deploy phase places a temporary hold on incoming requests and transitions the site to maintenance mode. The deploy phase uses the new containers and, after mounting the file system, opens network connections, activates the services defined in the relationships section of the file, and runs the deploy hooks defined in the file. Everything is read only, except for directories defined in the file. By default, the mounts property includes the following directories:

  • app/etc—contains the env.php and config.php configuration files
  • pub/media—contains all media data, such as Magento products or categories
  • pub/static—contains generated static files
  • var—contains temporary files created during Magento runtime

All other directories have read-only permissions. The new site becomes active at the end of the deploy phase as it transitions out of maintenance mode and releases the temporary hold on incoming requests.

Post-deploy phase Post-deploy phase

The post-deploy phase runs the post-deploy hooks defined in the file. Performing any action on this phase can affect site performance; however, you can use the WARM_UP_PAGES environment variable to populate the cache.
