运行 Hasura 控制台无法从 docker 运行

Question

我有一个 ruby​​ on rails 应用程序，我通过 docker-compose up 运行。我完全是 graphql 和 hasura 的菜鸟，我尝试了不同的方法来配置我的 docker，但我无法让它工作。

我的 docker-compose.yml：

    version: '3.6'

    services:
      postgres:
        image: postgis/postgis:latest
        restart: always
        ports:
        - "5434:5432"
        volumes:
        - ./init.sql:/docker-entrypoint-initdb.d/init.sql
        environment:
          PG_HOST_AUTH_METHOD: "trust"
          
      graphql-engine:
        image: hasura/graphql-engine:v1.2.2.cli-migrations-v2
        restart: always
        ports:
        - "8081:8080"
        volumes:
          - ./metadata:/hasura-metadata
        environment:
          HSR_GQL_DB_URL: "postgres://postgres@postgres/db-dev-name"
          HSR_GQL_ADMIN_SECRET: secret
        env_file:
          - .env
          
      server:
        build: .
        depends_on:
        - "postgres"
        command: bundle exec rails server -p 8081 -b 0.0.0.0
        ports:
          - "8080:8081"
        volumes:
          - ./:/server
          - gem_cache:/usr/local/bundle/gems
          - node_modules:/server/node_modules
        env_file:
          - .env
          
    volumes:
      gem_cache:
      node_modules:

config.yml:

    version: 2
    endpoint: http://localhost:8080
    metadata_directory: metadata
    actions:
      kind: synchronous
      handler_webhook_baseurl: http://localhost:8080

Docker 日志服务器显示：

Listening on tcp://0.0.0.0:8081

我可以在 docker-compose up 后访问应用程序 http://localhost:8080/server/

检查数据库连接，它也可以在数据库管理器 GUI 中的端口 :5434 访问。

但是当我尝试执行hasura console --admin-secret secret 时，浏览器上的 hasura 控制台没有显示。我只是在不同的日志上收到此错误：

我尝试通过浏览器访问 http://localhost:8081//console/api-explorer，似乎 graphql 容器正在获取请求，但仍然不会显示 hasura 控制台

                "code": "not-found"
            },

            "method": "GET",
            "content_encoding": null
        }
    }

我尝试将 HSR_GQL_DB_URL 设置为 postgres / localhost:5432 以及 postgis:// 而不是 postgres://。 我也尝试将 config.yml 端点字段更改为 http://localhost:8080/server/ 但这些也不起作用。

也许有点晚了，但无论如何：

根据GraphQL engine server config reference -> Command config 下的文档，您需要设置HASURA_GRAPHQL_ENABLE_CONSOLE 环境变量以启用/console 服务的控制台。或者对于hasura serve 命令，将--enable-console 选项设置为true：

Flag	ENV variable	Description
...	...	...
--enable-console <true|false>	HASURA_GRAPHQL_ENABLE_CONSOLE	Enable the Hasura Console (served by the server on / and /console) (default: false)
...	...	...

所以对于你的docker-compose.yml：

...
      graphql-engine:
        image: hasura/graphql-engine:v1.2.2.cli-migrations-v2
        restart: always
        ports:
        - "8081:8080"
        volumes:
          - ./metadata:/hasura-metadata
        environment:
          HSR_GQL_DB_URL: "postgres://postgres@postgres/db-dev-name"
          HSR_GQL_ADMIN_SECRET: secret
          HASURA_GRAPHQL_ENABLE_CONSOLE: "true" # add this
        env_file:
          - .env
...

我还阅读了某处以确保在 Docker 相关情况下使用环境变量时引用 true 和 false 值。这对我有用，所以我会坚持下去。试试看。
