sh: locale: not found

[bkuhl]

I have the 9.6-alpine container running (I've also tried just using 9.6) and am running into a locale issue.

Kubernetes Configuration

      - name: postgres
        image: postgres:9.6-alpine
        imagePullPolicy: IfNotPresent
        env:
          - { name: "POSTGRES_DB", value: "app_db" }
          - { name: "POSTGRES_USER", value: "db_user" }
          - { name: "POSTGRES_PASSWORD", valueFrom: { secretKeyRef: { name: laravel-starter-secrets, key: db.password }} }

Container Output

The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.
 The database cluster will be initialized with locale "en_US.utf8".
The default database encoding has accordingly been set to "UTF8".
The default text search configuration will be set to "english".
 Data page checksums are disabled.

--auth-local and --auth-host, the next time you run initdb.

 Success. You can now start the database server using:
     pg_ctl -D /var/lib/postgresql/data -l logfile start

I'm unsure how to pass --debug given the initialization script in this container. How can I debug what's happening here? My assumption is that the locale issue is preventing the container from running since I don't see any other issues in this output.

Nothing is wrong, this is the natural startup of the image. The entrypoint starts PostgreSQL server as a background process that only listens on localhost, then after completing the user and database creation (and running any scripts in /docker-entrypoint-initdb.d/) it then shuts down the limited PostgreSQL server. It then replaces the running bash process (via exec) with a new start of PostgreSQL server that listens publicly which should be just a few lines later in your logs after the "PostgreSQL init process complete; ready for start up."
