Docker swarm:在堆栈部署期间忽略 docker compose 文件中的“构建"配置 [英] Docker swarm: 'build' configuration in docker compose file ignored during stack deployment

问题描述

我们创建了一个包含多个服务的 docker compose 文件.这些服务的图像是使用构建"配置选项在运行时构建的.相应的 Dockerfile(s) 在各自的目录中给出.

We have created a docker compose file with multiple services. The images for these services are built in runtime using 'build' configuration option. The corresponding Dockerfile(s) are given in the respective directories.

示例 docker compose 文件...

Sample docker compose file...

version: '3'
services:
  db2server:
    build: ./db2server
    ports:
      - "50005:50000"
    command: ["db2start"]
  appruntime:
    build: ./appruntime
    depends_on:
     - db2server

此 docker compose 文件可与 docker-compose 命令配合使用.

This docker compose file works with docker-compose command.

• 图像是在运行时从 db2server 中存在的 Dockerfile 构建的 &appruntime 目录
• 这些映像部署在主机中

• The images are built in runtime from the Dockerfile(s) present in db2server & appruntime directories
• These images get deployed in the host machine

但是当我们尝试在 docker swarm 中部署它时，会抛出以下错误...

But when we try to deploy this in a docker swarm, the following error is thrown...

docker stack deploy -c/home/docker/docker-compose.yml app

docker stack deploy -c /home/docker/docker-compose.yml app

Ignoring unsupported options: build

Creating network app_default
Creating service app_db2server
failed to create service app_db2server: Error response from daemon: rpc error: code = InvalidArgument desc = ContainerSpec: image reference must be provided

在 docker swarm 中的堆栈部署期间似乎忽略了构建"配置选项.

Looks like the 'build' configuration option is ignored during stack deployment in docker swarm.

我们如何在 docker swarm 中部署 docker compose 文件中定义的这些服务(带有构建选项).

How can we deploy these services (with build option) defined in docker compose file in a docker swarm.

推荐答案

简短的回答是，您不能将 build 命令与 docker stack deploy 一起使用.

Short answer is, you can not use the build command with docker stack deploy.

来自 docs:

注意:docker stack 命令build 选项在使用(版本 3)Compose 文件以 swarm 模式部署堆栈时会被忽略.docker stack 命令只接受预先构建的图像.

Note: The docker stack command build option is ignored when deploying a stack in swarm mode with a (version 3) Compose file. The docker stack command accepts only pre-built images.

另一种方法是在部署 swarm 集群之前构建 docker 映像.

An alternative is to build the docker image before deploying the your swarm cluster.

使用 docker build 命令创建泊坞窗图像；将创建的镜像推送到(公共或私有)docker registry；并在您的 docker compose 文件中引用它.

Use the docker build command to create the docker image; Push the created image to a (public or private) docker registry; and reference it in your docker compose file.
