docker-compose，无需启动容器即可重建映像

Question

我泊坞窗组成，可以如下定义上下文

version: '3'
services:
    node1:
            build: node1
            image: node1
            container_name: node1

    node2:
            build: node2
            image: node2
            container_name: node2

其中build是指包含Dockerfile和构建资源的目录。 通过使用命令docker-compose up -d --build可以重建映像并重新启动更改的容器。 但是使用下面的docker-compose文件，是否可以仅构建映像而不启动它们，并且最好选择要构建或全部构建的映像？

Answer 1

您可以构建特定的服务而无需像这样启动它们：

docker-compose build node1

要构建它们：

docker-compose build

Answer 2

您也可以尝试docker-compose up --no-start
它将执行构建，创建网络，创建卷而不启动容器。

Usage: up [options] [--scale SERVICE=NUM...] [SERVICE...]

Options:
    -d, --detach               Detached mode: Run containers in the background,
                               print new container names. Incompatible with
                               --abort-on-container-exit.
    --no-color                 Produce monochrome output.
    --quiet-pull               Pull without printing progress information
    --no-deps                  Don't start linked services.
    --force-recreate           Recreate containers even if their configuration
                               and image haven't changed.
    --always-recreate-deps     Recreate dependent containers.
                               Incompatible with --no-recreate.
    --no-recreate              If containers already exist, don't recreate
                               them. Incompatible with --force-recreate and -V.
    --no-build                 Don't build an image, even if it's missing.
    --no-start                 Don't start the services after creating them.
