How to Pull all docker container images from docker repo at once?

问题

I have a private docker repo in which i have 10 container images stored. I want to pull all images to a machine. is there a way i can pull all images from a repo with a single command? some command like

docker pull  xx.xx.com/reponame/*

while researching I found ways to pull all tags of a single image; but no luck so far on all images

回答1:

Try this (it will update images that does not have running containers directly attached to them)

docker images | awk '(NR>1) && ($2!~/none/) {print $1":"$2}' | xargs -L1 docker pull

Try out this line out first to see what images will be covered:

docker images | awk '(NR>1) && ($2!~/none/) {print $1":"$2}'

回答2:

Regarding the docker documentation of the command: docker pull, you could use the option

--all-tags

to download all tagged images in the repository.

In your case, it would be :

docker pull --all-tags  xx.xx.com/reponame

Could 'hack' this with docker-compose.

# docker-compose.yml
version: '3.1'
services:
  a:
    image: a-image
  b:
    image: b-image
  c:
    image: c-image
# .....

docker-compose pull --parallel

Run below shell script to pull ALL DOCKER IMAGES with ALL TAGS from a Docker Registry at once,

SHELL SCRIPT:

#/bin/bash
set-x
registry="registry name/ip:port"
repos=`curl -u cloudfx:cFx2018Aug http://$registry/v2/_catalog?n=300 | jq '.repositories[]' | tr -d '"'`
for repo in $repos; do 
   docker pull --all-tags $registry/$repo;
done

Easy.

Install jq to parse JSON, edit the REGISTRY variable and run this script:

#!/bin/sh

REGISTRY="http://registry:5000"

for repo in $(curl -s $REGISTRY/v2/_catalog | jq -r '.repositories[]') ; do
    for tag in $(curl -s $REGISTRY/v2/$repo/tags/list | jq -r '.tags[]') ; do
        docker pull $REGISTRY/$repo:$tag
    done
done

Not sure what type of command is a single command, one-liner?

for repo in repo1 repo2 repo3; do docker pull xx.xx.com/$repo; done
