docker-compose postgres genstart efter at have kørt scripts i docker-entrypoint-initdb.d

Kort sagt, dette sker med vilje; forfatteren gør det som en del af initialiseringen.

Det ser ud til, at nogle svar kan findes i billedets entrypoint shell-script:

_main() {
    # if first arg looks like a flag, assume we want to run postgres server
    if [ "${1:0:1}" = '-' ]; then
        set -- postgres "[email protected]"
    fi

    if [ "$1" = 'postgres' ] && ! _pg_want_help "[email protected]"; then
        docker_setup_env
        # setup data directories and permissions (when run as root)
        docker_create_db_directories
        if [ "$(id -u)" = '0' ]; then
            # then restart script as postgres user
            exec gosu postgres "$BASH_SOURCE" "[email protected]"
        fi

        # only run initialization on an empty data directory
        if [ -z "$DATABASE_ALREADY_EXISTS" ]; then
            docker_verify_minimum_env

            # check dir permissions to reduce likelihood of half-initialized database
            ls /docker-entrypoint-initdb.d/ > /dev/null

            docker_init_database_dir
            pg_setup_hba_conf

            # PGPASSWORD is required for psql when authentication is required for 'local' connections via pg_hba.conf and is otherwise harmless
            # e.g. when '--auth=md5' or '--auth-local=md5' is used in POSTGRES_INITDB_ARGS
            export PGPASSWORD="${PGPASSWORD:-$POSTGRES_PASSWORD}"
            docker_temp_server_start "[email protected]"

            docker_setup_db
            docker_process_init_files /docker-entrypoint-initdb.d/*

            docker_temp_server_stop
            unset PGPASSWORD

            echo
            echo 'PostgreSQL init process complete; ready for start up.'
            echo
        else
            echo
            echo 'PostgreSQL Database directory appears to contain a database; Skipping initialization'
            echo
        fi
    fi

    exec "[email protected]"
}

Med hensyn til "hvorfor?" Jeg tror, ​​det er på grund af ønsket om at køre som en mindre privilegeret bruger.

Du kan "løse" problemet ved at angive en volumen i Compose-filen som sådan:

    volumes:
       - ./data/pgsql:/var/lib/postgresql/data

Derefter vil den springe rutinen over for at sikre DATABASE_ALREADY_EXISTS .

Eller, hvis det ikke er nyttigt--du kan grave lidt mere i indgangs-scriptet.
