当我运行以下命令时,我希望退出代码为0,因为我的combined容器运行了一个成功退出代码为0的测试。

代码语言:javascript
运行
复制
docker-compose up --build --exit-code-from combined

不幸的是,即使在我的combined容器中的测试成功运行时,我也始终收到一个137的退出代码,并且我以0的退出代码退出了该容器(关于如何发生这种情况的更多详细信息,请在下面指定)。

下面是我的版本号:

代码语言:javascript
运行
复制
docker-compose version 1.25.0, build 0a186604

根据这个帖子,137的出口代码可能是由两个主要问题造成的。

  1. 容器收到了一个docker stop,应用程序没有很好地处理SIGTERM
  2. 容器内存不足(OOM)。

我知道137退出代码并不是因为我的容器内存用完了。当我运行docker inspect <container-id>时,我可以看到"OOMKilled“是假的,如下面的片段所示。我还有6GB的内存分配给Docker引擎,这对于我的应用程序来说已经足够了。

            "Restarting": false,
            "OOMKilled": false, <---- shows container did not run out of memory
            "Dead": false,
            "Pid": 0,
            "ExitCode": 137,
            "Error": "",

            "FinishedAt": "2019-12-12T01:44:11.5407553Z"
        },

我的容器不会退出docker stop,所以我认为第一个原因也与我的情况无关。

如何设置我的码头容器

我有两个码头集装箱:

  1. b-db -包含我的数据库
  2. b-组合-包含我的web应用程序和一系列测试,一旦容器启动并运行,这些测试就会运行。

我使用了一个docker-compose.yml文件来启动这两个容器。

代码语言:javascript
运行
复制
version: '3'
services:
    db:
        build:
            context: .
            dockerfile: ./docker/db/Dockerfile
        container_name: b-db
        restart: unless-stopped
        volumes:     
            - dbdata:/data/db
        ports:
            - "27017:27017"
        networks:
            - app-network

    combined:
        build:
            context: .
            dockerfile: ./docker/combined/Dockerfile
        container_name: b-combined
        restart: unless-stopped
        env_file: .env
        ports:
            - "5000:5000"
            - "8080:8080"
        networks:
            - app-network
        depends_on:
            - db

networks:
    app-network:
        driver: bridge

    dbdata:

下面是combined服务在docker-compose.yml中的Dockerfile。

代码语言:javascript
运行
复制
FROM cypress/included:3.4.1

WORKDIR /usr/src/app

COPY package*.json ./

RUN npm install

COPY . .

EXPOSE 5000

RUN npm install -g history-server nodemon

RUN npm run build-test

EXPOSE 8080

COPY ./docker/combined/init.sh /scripts/init.sh

RUN ["chmod", "+x", "/scripts/init.sh"]

ENTRYPOINT [ "/scripts/init.sh" ]

下面是我的init.sh文件中的内容。

代码语言:javascript
运行

#!/bin/bash

# Start back end server that interacts with DB
nodemon -L server &
back_pid=$!

# Run tests
NODE_ENV=test $(npm bin)/cypress run --config video=false --browser chrome

# Error code of the test
test_exit_code=$?

echo "TEST ENDED WITH EXIT CODE OF: $test_exit_code"

# End front and backend server
kill -9 $front_pid
kill -9 $back_pid

# Exit with the error code of the test
echo "EXITING SCRIPT WITH EXIT CODE OF: $test_exit_code"
exit "$test_exit_code"

下面是我的db服务的Dockerfile。它所做的一切就是将一些本地数据复制到Docker容器中,然后使用这些数据初始化数据库。

代码语言:javascript
运行
复制
FROM  mongo:3.6.14-xenial

COPY ./dump/ /tmp/dump/

COPY mongo_restore.sh /docker-entrypoint-initdb.d/

RUN chmod 777 /docker-entrypoint-initdb.d/mongo_restore.sh

下面是mongo_restore.sh中的内容。

代码语言:javascript
运行
复制
#!/bin/bash
# Creates db using copied data
mongorestore /tmp/dump

下面是我运行docker-compose up --build --exit-code-from combined; echo $?时输出的最后几行。

代码语言:javascript
运行
复制
...

Stopping b-combined   ... done
137

正如您在上面看到的,令人困惑的是,测试和脚本以0的退出代码结束,因为我的所有测试都成功通过了,但是容器仍然以137.的退出代码退出。

更令人困惑的是,当我从我的init.sh 文件中注释掉下面一行(它运行我的Cypress集成测试)时,容器将使用0退出代码退出,如下所示。

代码语言:javascript
运行
复制
NODE_ENV=test $(npm bin)/cypress run --config video=false --browser chrome

下面是我从init.sh中注释掉/删除上面一行时收到的输出,这是一个运行我的Cypress集成测试的命令。

Stopping b-combined   ... done

如何使我在测试成功运行时返回一个零退出代码,当测试失败时返回一个非零退出代码?

编辑:

在调试模式下运行了下面的Docker -复合命令之后,我注意到b-db似乎在关闭时遇到了一些问题,因此可能会收到来自Docker的SIGKILL信号。

代码语言:javascript
运行
复制
docker-compose --log-level DEBUG up --build --exit-code-from combined; echo $?

根据下面的输出,情况是否真的如此?

错误消息给我的印象是:Aborting on container exit...

来自船坞-撰写文档

如果停止任何容器,--abort-on-container-exit将停止所有容器。

你在用这面旗子做码头工吗?如果是这样的话,想想它意味着什么。

一旦b-combined完成,它就会退出。这意味着容器b-db也将被迫停止。尽管b-combined返回时带有退出代码0,但mongodb可能无法很好地处理b-db强制关闭。

编辑:我刚刚意识到命令行中有--exit-code-from。这意味着--abort-on-container-exit

解决方案b-db需要更多时间优雅地退出。使用docker-compose up --timeout 600可以避免错误。

Docker退出代码137意味着Docker没有足够的RAM来完成工作。

不幸的是,Docker消耗了大量的RAM。

这可能是RAM的问题,我使用Docker首选项增加了内存。从docker-compose up开始我的服务。服务器已经为我打开了,没有任何问题。
