Question

我是docker compose，可以按如下方式定义上下文

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

    node2:
            build: node2
            image: node2
            container_name: node2

其中build指的是包含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已更改的容器。但是使用以下docker-compose文件，是否可以仅在不启动它们的情况下构建图像，并且最好选择构建或构建所有图像？

Answer 1

您可以在不启动它们的情况下构建特定服务：

docker-compose build node1

全部构建它们：

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，创建卷而无需启动容器。

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.

docker-compose，重建图像而不启动容器
