ubuntu@center-kitchen:/data/postsql-redis$ sudo docker exec -it 1676ca9b2eb9 psql -U postgres -d postgres psql: FATAL: role "postgres" does not exist

使用docker-compose.yml创建postgresSQL,登录psql容器时提示缺少postgres角色：

ubuntu@center-kitchen:/data/postsql-redis$ sudo docker exec -it 1676ca9b2eb9 psql -U postgres -d postgres

psql: FATAL:  role "postgres" does not exist

排查了很久，查看了官方文档，找到了问题，缺个参数：privileged: true(红色字体所示)，贴上我的yml文件：

version: '2.3'

networks:

    ic_net:

      name: ic_net

      ipam:

        driver: default

        config:

          - subnet: "172.20.0.0/24"

services:

  redis:

    image: redis:4

    restart: always

    container_name: pigfarm_redis

    ports:

      - 6379:6379

    logging:

      driver: "json-file"

      options:

        max-size: "100m"

    networks:

      - ic_net

 

  postgres:

    image: postgres:9.6

    restart: always

    container_name: pigfarm_postgres

    ports:

      - 5432:5432

    privileged: true

    environment:

      POSTGRES_PASSWORD: postgres

      PGDATA: /var/lib/postgresql/data/pgdata

    volumes:

      - ./pg_data/data:/var/lib/postgresql/data/pgdata

    logging:

      driver: "json-file"

    networks:

      - ic_net

ubuntu@center-kitchen:/data/postsql-redis$ sudo docker-compose down

ubuntu@center-kitchen:/data/postsql-redis$ sudo docker-compose up -d

重启后，登录验证，成功进入数据库，如下所示：

ubuntu@center-kitchen:/data/postsql-redis$ sudo docker exec -it bd04bb35f624 psql -U postgres -d postgres

psql (9.6.17)

Type "help" for help.

 postgres=# 

结束。
