Update (pull) all docker images at once

Question

是否有命令可以在终端中一次更新（拉取）所有下载的 Docker 镜像？

Answer 1

No, there is no built-in command to pull all docker images at once .

But you can try this (multiline) bash using docker --format :

for image in $(docker images --format "{{.Repository}}:{{.Tag}}" | grep -v '<none>')
do
  docker pull $image
done

Or in one line:

for image in $(docker images --format "{{.Repository}}:{{.Tag}}" | grep -v '<none>'); do docker pull $image; done;

Answer 2

你可以使用这个：

docker images | awk '{print $1":"$2}' | grep -v REPOSITORY | xargs -L1 docker pull
