docker - Kubernetes 构成

Question

您好，我正在使用 AWS EKS 开发 kubernetes。当我将 docker-compose 文件转换为 kompose 文件时，我遇到了 kompose 文件的问题，我遇到了卷挂载点问题，而且当我运行命令时，kompose up 它询问用户名我应该提供哪个凭据。

这是我的 docker-compose.yml

services:
    cms-db:
        image: mysql:5.6
        volumes:
            - "./shared/db:/var/lib/mysql"
        restart: always
        environment:
            - MYSQL_DATABASE=cms
            - MYSQL_USER=cms
            - MYSQL_RANDOM_ROOT_PASSWORD=yes
        mem_limit: 1g
        env_file: config.env
    cms-xmr:
        image: xibosignage/xibo-xmr:release-0.7
        ports:
            - "9505:9505"
        restart: always
        mem_limit: 256m
        env_file: config.env
    cms-web:
        image: xibosignage/xibo-cms:release-1.8.10
        volumes:
            - "./shared/cms/custom:/var/www/cms/custom"
            - "./shared/backup:/var/www/backup"
            - "./shared/cms/web/theme/custom:/var/www/cms/web/theme/custom"
            - "./shared/cms/library:/var/www/cms/library"
            - "./shared/cms/web/userscripts:/var/www/cms/web/userscripts"
        restart: always
        links:
            - cms-db:mysql
            - cms-xmr:50001
        environment:
            - XMR_HOST=cms-xmr
        env_file: config.env
        ports:
            - "80:80"
        mem_limit: 1g

将配置应用到 Kubernetes 集群的更好方法是转换它，检查 YAML 文件，必要时调整它们，然后使用 kubectl 应用它们。

我在 Mac 上使用 kompose v1.16.0 测试了转换，我不得不从 docker-compose.yml 中删除 mem_limit 选项文件以成功完成它。

$ mkdir export
$ kompose -v convert -f docker-compose.yml -o export

将在 export 目录中创建 14 个文件。

不支持本地路径 - 将改为创建持久卷声明(将出现警告)。持久卷声明默认为 100Mi。编辑声明 YAML 文件并在必要时增加大小。

现在您可以使用以下方式将您的配置部署到 Kubernetes 集群:

kubectl create -f export/
