postgresql 容器未启动：chmod：更改“/bitnami/postgresql/data”的权限：不允许操作

Question

bitnami/postgresql 无法启动卷挂载。我使用的是10.14.0版本的官方docker镜像。

容器在没有卷安装的情况下启动：

docker run --rm --name postgresql -e POSTGRESQL_PASSWORD=password123 bitnami/postgresql:10.14.0

带卷安装

docker run --rm --name postgresql -v /postgresql:/bitnami/postgresql -e POSTGRESQL_PASSWORD=password123 bitnami/postgresql:10.14.0

使用 docker-compose 文件

postgresql:
      image: bitnami/postgresql:10.14.0
      container_name: postgresql
      ports:
        - 5432:5432
      environment: 
        - POSTGRESQL_REPLICATION_MODE=master
        - POSTGRESQL_REPLICATION_USER=repl_user
        - POSTGRESQL_REPLICATION_PASSWORD=repl_password
        - POSTGRESQL_USERNAME=my_user
        - POSTGRESQL_PASSWORD=my_password
        - POSTGRESQL_DATABASE=my_database
        - POSTGRESQL_SYNCHRONOUS_COMMIT_MODE=on
        - POSTGRESQL_NUM_SYNCHRONOUS_REPLICAS=1
      volumes:
        - /postgresql:/bitnami/postgresql
      restart: always

输出：

docker-compose up

我无法找到任何解决方案。其他容器似乎没有这个问题。如果有人找到解决此问题的方法，请帮忙。

Bitnami 工程师在这里，

由于 Bitnami PostgreSQL 容器是非 root 容器，因此 id 1001 的用户需要对您正在挂载的本地文件夹具有写入权限。

sudo chown -R 1001:1001 /postgresql
