### Disabling `docker pull` calls ### Disabling `docker image pull` calls
If you wish to disable the `docker pull` calls that the plugin triggers, you may set the `POSTGRES_DISABLE_PULL` environment variable to `true`. Once disabled, you will need to pull the service image you wish to deploy as shown in the `stderr` output. If you wish to disable the `docker image pull` calls that the plugin triggers, you may set the `POSTGRES_DISABLE_PULL` environment variable to `true`. Once disabled, you will need to pull the service image you wish to deploy as shown in the `stderr` output.
Please ensure the proper images are in place when `docker pull` is disabled. Please ensure the proper images are in place when `docker image pull` is disabled.
