Docker 명령 줄의 Docker 레지스트리에서 특정 태그가있는 Docker 이미지를 찾으려면 어떻게해야합니까?

---

Docker 이미지에 대한 특정 태그를 찾으려고합니다. 명령 줄에서 어떻게 할 수 있습니까? 모든 다운로드를 피하고 불필요한 이미지를 제거하려고합니다.

공식 우분투 릴리스 https://registry.hub.docker.com/_/ubuntu/ 에는 몇 가지 태그 (릴리스)가 있지만 명령 줄에서 검색하면

user@ubuntu:~$ docker search ubuntu | grep ^ubuntu
ubuntu              Official Ubuntu base image                          354
ubuntu-upstart      Upstart is an event-based replacement for ...   7
ubuntufan/ping                                                0
ubuntu-debootstrap                                                   0

또한 명령 줄 search https://docs.docker.com/engine/reference/commandline/search/ 의 도움말에서 작동 방법에 대한 단서가 없습니까?

docker search명령 에서 가능 합니까?

원시 명령을 사용하여 Docker 레지스트리 API 를 통해 검색 하면 정보를 가져올 수 있습니다.

   $ curl https://registry.hub.docker.com//v1/repositories/ubuntu/tags | python -mjson.tool
   [
    {
        "layer": "ef83896b",
        "name": "latest"
    },
    .....
    {
        "layer": "463ff6be",
        "name": "raring"
    },
    {
        "layer": "195eb90b",
        "name": "saucy"
    },
    {
        "layer": "ef83896b",
        "name": "trusty"
    }
]

---

내가 아는 한 CLI는 저장소에서 태그 검색 / 나열을 허용하지 않습니다.

하지만 원하는 태그를 알고 있다면 콜론과 이미지 이름을 추가하여 명시 적으로 가져올 수 있습니다. docker pull ubuntu:saucy

CoreOS jq를 사용하면 JSON 데이터를 구문 분석 할 수 있습니다.

이전에했던 것처럼 library/centos

$ curl -s -S 'https://registry.hub.docker.com/v2/repositories/library/centos/tags/' | jq '."results"[]["name"]' |sort
"6"
"6.7"
"centos5"
"centos5.11"
"centos6"
"centos6.6"
"centos6.7"
"centos7.0.1406"
"centos7.1.1503"
"latest"

이제 더 깨끗한 v2 API를 사용할 수 있으며 이것이 제가 예제에서 사용하고있는 것입니다. 간단한 스크립트를 작성하겠습니다 docker_remote_tags.

#!/usr/bin/bash
curl -s -S "https://registry.hub.docker.com/v2/repositories/library/$@/tags/" | jq '."results"[]["name"]' |sort

다음을 활성화합니다.

$ ./docker_remote_tags library/centos
"6"
"6.7"
"centos5"
"centos5.11"
"centos6"
"centos6.6"
"centos6.7"
"centos7.0.1406"
"centos7.1.1503"
"latest"

참고:

jq: https://stedolan.github.io/jq/ |apt-get install jq

A) 내가 가지고 있지 않고 설치하고 싶지 않은 외부 라이브러리가 필요했기 때문에 위의 솔루션이 마음에 들지 않았습니다. B) 모든 페이지를 얻지 못했습니다.

Docker API는 요청 당 항목을 100 개로 제한합니다. 이것은 각 "다음"항목을 ​​반복하여 모두 가져옵니다 (Python의 경우 7 페이지, 다른 항목은 다소 다를 수 있습니다.).

정말로 스팸을 보내고 싶다면 | cut -d '-' -f 1마지막 줄에서 제거 하면 모든 것을 볼 수 있습니다.

url=https://registry.hub.docker.com/v2/repositories/library/redis/tags/?page_size=100 `# Initial url` ; \
( \
  while [ ! -z $url ]; do `# Keep looping until the variable url is empty` \
    >&2 echo -n "." `# Every iteration of the loop prints out a single dot to show progress as it got through all the pages (this is inline dot)` ; \
    content=$(curl -s $url | python -c 'import sys, json; data = json.load(sys.stdin); print(data.get("next", "") or ""); print("\n".join([x["name"] for x in data["results"]]))') `# Curl the URL and pipe the output to Python. Python will parse the JSON and print the very first line as the next URL (it will leave it blank if there are no more pages) then continue to loop over the results extracting only the name; all will be stored in a variable called content` ; \
    url=$(echo "$content" | head -n 1) `# Let's get the first line of content which contains the next URL for the loop to continue` ; \
    echo "$content" | tail -n +2 `# Print the content without the first line (yes +2 is counter intuitive)` ; \
  done; \
  >&2 echo `# Finally break the line of dots` ; \
) | cut -d '-' -f 1 | sort --version-sort | uniq;

샘플 출력 :

이 스크립트 (docker-show-repo-tags.sh)는 curl, sed, grep 및 sort가있는 Docker 지원 호스트에서 작동해야합니다. 이것은 저장소 태그 URL이 변경되었다는 사실을 반영하기 위해 업데이트되었습니다.

#!/bin/sh
#
# Simple script that will display Docker repository tags
# using basic tools: curl, sed, grep, and sort.
#
# Usage:
#   $ docker-show-repo-tags.sh ubuntu centos
for Repo in $* ; do
    curl -sS "https://hub.docker.com/r/library/$Repo/tags/" | \
        sed -e $'s/"tags":/\\\n"tags":/g' -e $'s/\]/\\\n\]/g' | \
        grep '^"tags"' | \
        grep '"library"' | \
        sed -e $'s/,/,\\\n/g' -e 's/,//g' -e 's/"//g' | \
        grep -v 'library:' | \
        sort -fu | \
        sed -e "s/^/${Repo}:/"
done

이 이전 버전은 더 이상 작동하지 않습니다.

#!/bin/sh
# WARNING: This no long works!
# Simple script that will display Docker repository tags.
#
# Usage:
#   $ docker-show-repo-tags.sh ubuntu centos
for Repo in $* ; do
  curl -s -S "https://registry.hub.docker.com/v2/repositories/library/$Repo/tags/" | \
    sed -e $'s/,/,\\\n/g' -e $'s/\[/\\\[\n/g' | \
    grep '"name"' | \
    awk -F\" '{print $4;}' | \
    sort -fu | \
    sed -e "s/^/${Repo}:/"
done

다음은 간단한 예의 출력입니다.

$ docker-show-repo-tags.sh centos | cat -n

     2    centos:5.11

필자는 PyTools GitHub repo 에서 사용 가능한 DockerHub repo 태그 검색을 단순화하는 명령 줄 도구를 작성했습니다 . 다양한 명령 줄 스위치와 함께 사용하는 것은 간단하지만 기본적으로는 다음과 같습니다.

./dockerhub_show_tags.py repo1 repo2

도커 이미지로도 사용할 수 있으며 여러 저장소를 사용할 수 있습니다.

docker run harisekhon/pytools dockerhub_show_tags.py centos ubuntu 

DockerHub

repo: centos
tags: 5.11
      6.6
      6.7
      7.0.1406
      7.1.1503
      centos5.11
      centos6.6
      centos6.7
      centos7.0.1406
      centos7.1.1503

repo: ubuntu
tags: latest
      14.04
      15.10
      16.04
      trusty
      trusty-20160503.1
      wily
      wily-20160503
      xenial
      xenial-20160503

스크립트에 포함하려면 -q / --quiet을 사용하여 일반 도커 명령과 같이 태그 만 가져옵니다.

./dockerhub_show_tags.py centos -q
5.11
6.6
6.7
7.0.1406
7.1.1503
centos5.11
centos6.6
centos6.7
centos7.0.1406

The v2 API seems to use some kind of pagination, so that it does not return all the available tags. This is clearly visible in projects such as python (or library/python). Even after quickly reading the documentation, I could not manage to work with the API correctly (maybe it is the wrong documentation).

Then I rewrote the script using the v1 API, and still using jq:

#!/bin/bash

repo="$1"

if [[ "${repo}" != */* ]]; then
    repo="library/${repo}"
fi

url="https://registry.hub.docker.com/v1/repositories/${repo}/tags"
curl -s -S "${url}" | jq '.[]["name"]' | sed 's/^"\(.*\)"$/\1/' | sort

The full script is available at: https://bitbucket.org/denilsonsa/small_scripts/src/default/docker_remote_tags.sh

I've also written (in Python) an improved version that aggregates tags that point to the same version: https://bitbucket.org/denilsonsa/small_scripts/src/default/docker_remote_tags.py

Add this function to your .zshrc file or run the command mannually

#usage list-dh-tags <repo>
#example: list-dh-tags node
function list-dh-tags(){
    wget -q https://registry.hub.docker.com/v1/repositories/$1/tags -O -  | sed -e 's/[][]//g' -e 's/"//g' -e 's/ //g' | tr '}' '\n'  | awk -F: '{print $3}'
}

thanks to this -> How to list all tags for a Docker image on a remote registry?

Reimplementation of the previous post, using Python over sed/awk:

for Repo in $* ; do
    tags=$(curl -s -S "https://registry.hub.docker.com/v2/repositories/library/$Repo/tags/")
    python - <<EOF

import json

tags = [t['name'] for t in json.loads('''$tags''')['results']]
tags.sort()
for tag in tags:
    print "{}:{}".format('$Repo', tag)
EOF
done

For a script that works with Oauth bearer tokens on Docker hub, try this:

You can use Visual Studio Code to provide autocomplete for available docker images and tags. However, this requires that you type the first letter of a tag in order to see autocomplete suggestions.

For example when writing FROM ubuntu it offers autocomplete suggestions like ubuntu, ubuntu-debootstrap and ubuntu-upstart. When writing FROM ubuntu:a it offers an autocomplete suggestions like ubuntu:artful and ubuntu:artful-20170511.1
