一：Docker私有倉庫安裝
1、 下載鏡像是有鏡像倉庫：
[root@localhost ~]# systemctl start docker#如果已經有鏡像了，強制刪除原來的鏡像的方式如下：[root@xxx-pub /]# docker rmi -f docker.io/registryUntagged: docker.io/registry:latestUntagged: docker.io/registry@sha256:51bb55f23ef7e25ac9b8313b139a8dd45baa832943c8ad8f7da2ddad6355b3c8[root@xxx-pub /]##開始下載最新的鏡像。[root@localhost ~]# docker pull registryUsing default tag: latestlatest: Pulling from library/registry4064ffdc82fe: Pull complete c12c92d1c5a2: Pull complete 4fbc9b6835cc: Pull complete 765973b0f65f: Pull complete 3968771a7c3a: Pull complete Digest: sha256:20bbbc0f6384cf7dc6e292ccbe75935b73c92ec776543c970904bc60feceb129Status: Downloaded newer image for registry:latest[root@localhost ~]#
2、 啟動并且掛載鏡像倉庫到本地磁盤：
[root@xxx-pub /]# docker run -d -v /registry:/home/docker-registry -p 5000:5000 --restart=always --privileged=true --name registry registry:latestUnable to find image 'registry:latest' locallyTrying to pull repository docker.io/library/registry ... latest: Pulling from docker.io/library/registryDigest: sha256:51bb55f23ef7e25ac9b8313b139a8dd45baa832943c8ad8f7da2ddad6355b3c8Status: Downloaded newer image for docker.io/registry:latestb7bd2b14ed488936afe798be95f3cd56f604fb092d45cf6f4a58359bcad0d34c[root@xxx-pub /]#
為了持久化數據，將volume掛載到/home/docker-registry
3、 我們給一個本地鏡像打個標簽然后上傳：
查看本地有哪些鏡像：
[root@xxx-pub /]# docker imagesREPOSITORY TAG IMAGE ID CREATED SIZEdocker.io/centos centos7.5.1804 fdf13fa91c6e 4 weeks ago 200 MBdocker.io/registry latest b2b03e9146e1 2 months ago 33.3 MB[root@xxx-pub /]#
以docker.io/centos為案例。
[root@xxx-pub /]# docker tag fdf13fa91c6e localhost:5000/xxx-centos7.5.1804:1.0##localhost:5000表示倉庫地址，fdf13fa91c6e表示images id，xxx-centos7.5.1804表示鏡像名稱，1.0表示版本號。或：[root@xxx-pub /]# docker tag docker.io/centos:centos7.5.1804 localhost:5000/xxx-centos7.5.1804:1.0
4、 直接上傳：
[root@xxx-pub /]# docker push localhost:5000/xxx-centos7.5.1804:1.0The push refers to a repository [localhost:5000/xxx-centos7.5.1804]bcc97fbfc9e1: Pushed 1.0: digest: sha256:7c14180942615fef85cb5c8b1388e028be1a8f79694a5fa30a4025173e42ad61 size: 529[root@xxx-pub /]#
在PUSH的過程中可能報類似如下的錯誤（以下是網絡上的錯誤提示）：
[root@localhost ~]# docker push 192.168.174.128:5000/hello:latestThe push refers to a repository [192.168.174.128:5000/hello]unable to ping registry endpoint https://192.168.174.128:5000/v0/v2 ping attempt failed with error: Get https://192.168.174.128:5000/v2/: http: server gave HTTP response to HTTPS client v1 ping attempt failed with error: Get https://192.168.174.128:5000/v1/_ping: http: server gave HTTP response to HTTPS client[root@localhost ~]#
解決辦法：
使用的是https,修改/etc/sysconfig/docker(這里是Centos7下的docker)文件，加上ADD_REGISTRY='–add-registry 192.168.18.162:5000',INSECURE_REGISTRY='–insecure-registry 192.168.18.162:5000' (上面是歷史的docker版本的配置)，如下圖：
但是在新的docker容器倉庫的配置中，自己的docker容器中的配置采用（這里在docker registry和另外pull鏡像的機器上都指定如下的配置）：
指定完成之后，要重啟docker，重啟的配置如下：
[root@youx-pub volumes]# systemctl restart docker
另外：查看一下docker.service,查看一下配置文件：
[root@youx-pub registry]find / -name docker.service/sys/fs/cgroup/memory/system.slice/docker.service/sys/fs/cgroup/devices/system.slice/docker.service/sys/fs/cgroup/blkio/system.slice/docker.service/sys/fs/cgroup/cpu,cpuacct/system.slice/docker.service/sys/fs/cgroup/pids/system.slice/docker.service/sys/fs/cgroup/systemd/system.slice/docker.service/usr/lib/systemd/system/docker.service[root@youx-pub registry]# vim /usr/lib/systemd/system/docker.service
然后執行一下：
#因為可以用于systemctl啟動的docker.service文件變化了，所以得執行以下配置。然后執行docker的重啟工作systemctl daemon-reloadsystemctl restart docker
如果還是報如下錯誤：
[root@youx-pub registry]# docker push 192.168.18.162:5000/nginx:1.2The push refers to a repository [192.168.18.162:5000/nginx]Get https://192.168.18.162:5000/v1/_ping: http: server gave HTTP response to HTTPS client[root@youx-pub registry]#
解決辦法是：
在/etc/docker下創建daemon.json，內容是：
{"insecure-registries":["192.168.18.162:5000"]}然后再重啟docker容器：
[root@youx-pub volumes]# systemctl restart docker
5、 上傳完成，我們可以查看一下掛載目錄是否有鏡像：
[root@xxx-pub docker-registry]# pwd/home/docker-registry[root@xxx-pub docker-registry] # ls /registry/Docker
6、 關于本地鏡像的查看：
[root@xxx-pub docker-registry]# curl http://192.168.18.162:5000/v2/_catalog{"repositories":["xxx-centos7.5.1804","xxx-centos7.5.1804-v1.0"]}[root@xxx-pub docker-registry]#7、 看到有兩個鏡像，我們要獲取他的標簽信息以便下載呢：
[root@xxx-pub docker-registry]# curl http://192.168.18.162:5000/v2/xxx-centos7.5.1804/tags/list{"name":"xxx-centos7.5.1804","tags":["1.0"]}[root@xxx-pub docker-registry]#8、 然后我們直接下載鏡像(到另電腦上)：
[root@bigdata2 ~]# docker pull 192.168.18.162:5000/youx-centos7.5.1804:1.0Using default tag: latestTrying to pull repository 192.168.18.162/youx-centos7.5.1804 ... Get https://192.168.18.162/v1/_ping: dial tcp 192.168.18.162:443: getsockopt: no route to host[root@bigdata2 ~]#
如果出現上面的情況，解決辦法是：
編譯：
[root@youx-pub volumes]# vim /etc/containers/registries.conf 這個文件。舊的是編輯：/etc/sysconfig/docker 這個文件
然后重啟docker
[root@youx-pub volumes]# systemctl restart docker
然后發現可以pull了
#要注意的是，這里的地址是：倉庫地址：倉庫端口號/REPOSITORY:TAG[root@bigdata2 ~]# docker pull 192.168.18.162:5000/youx-centos7.5.1804:1.0
如果還不行，需要修改/etc/docker/daemon.json,內容如下：
[root@bigdata2 docker]# cat daemon.json {"insecure-registries":["192.168.18.162:5000"]}二、從另外一臺機器上上傳鏡像到docker鏡像倉庫：
[root@bigdata2 ~]# docker tag centos7-jdk8-nginx:1.0 192.168.18.162:5000/centos7-jdk8-nginx:1.0[root@bigdata2 ~]# docker imagesREPOSITORY TAG IMAGE ID CREATED SIZE192.168.18.162:5000/centos7-jdk8-nginx 1.0 bcacd65e2a2e 2 minutes ago 2.18 GB[root@bigdata2 ~]# docker push 192.168.18.162:5000/centos7-jdk8-nginx:1.0The push refers to a repository [192.168.18.162:5000/centos7-jdk8-nginx]f018e9c38a66: Pushed 2a47dcd341ef: Pushed c5dea3bc729a: Pushed bcc97fbfc9e1: Pushed 1.0: digest: sha256:d907ff2f8eb590209700c01ce85c78d0bc778a4238539d747e4667d68cb52102 size: 1163[root@bigdata2 ~]#
然后進入docker鏡像倉庫所在位置：
[root@youx-pub registry]# curl http://192.168.18.162:5000/v2/_catalog{"repositories":["centos7-jdk8-nginx","nginx"]}[root@youx-pub registry]# curl http://192.168.18.162:5000/v2/centos7-jdk8-nginx/tags/list{"name":"centos7-jdk8-nginx","tags":["1.0"]}[root@youx-pub registry]#三、本地鏡像如何刪除，正常是不提供刪除功能的，所以使用第三方的插件來進行刪除
插件github上的位置：
https://github.com/burnettk/delete-docker-registry-image
1、下載資源
[root@master registry]# curl https://raw.githubusercontent.com/burnettk/delete-docker-registry-image/master/delete_docker_registry_image.py | sudo tee /usr/local/bin/delete_docker_registry_image >/dev/nullsudo chmod a+x /usr/local/bin/delete_docker_registry_image
2、 設置相關環節變量：
查找REGISTRY_DATA_DIR，命令：[root@youx-pub registry]# find / -name registry[root@youx-pub registry]# find / -name registry/var/lib/docker/overlay2/d72320cd67b42f7ae66342cc6dedab7abe5e89106de8c4919ec8c5a6e5940b09/diff/var/lib/ucf/registry/var/lib/docker/overlay2/92211417089f7be8239def550e1e89ce3f0e50ac57f2c36ba723ca312ea06ae3/diff/bin/registry/var/lib/docker/overlay2/c1716aea0b380eb94ead9aa02552769acd4c3dac8e6dab735997f1709ce79a33/diff/etc/docker/registry/var/lib/docker/overlay2/46f719f01255c431b4343e78607341d6d66ea482bc6d03c3b4e05e7413f46be6/diff/var/lib/registry/var/lib/docker/overlay2/46f719f01255c431b4343e78607341d6d66ea482bc6d03c3b4e05e7413f46be6/merged/bin/registry/var/lib/docker/overlay2/46f719f01255c431b4343e78607341d6d66ea482bc6d03c3b4e05e7413f46be6/merged/etc/docker/registry/var/lib/docker/overlay2/46f719f01255c431b4343e78607341d6d66ea482bc6d03c3b4e05e7413f46be6/merged/var/lib/registry/var/lib/docker/volumes/1522d54c954c755250cb71686cacd9714cd3d0f0c706ec18c1e490c7881fe713/_data/docker/registry/opt/data/registry/registry[root@youx-pub registry]#發現[root@youx-pub repositories]# pwd/var/lib/docker/volumes/1522d54c954c755250cb71686cacd9714cd3d0f0c706ec18c1e490c7881fe713/_data/docker/registry/v2/repositories[root@youx-pub repositories]# lscentos7-jdk8-nginx nginx[root@youx-pub repositories]#所以設置鏡像倉庫的位置為：[root@master registry]# export REGISTRY_DATA_DIR=/var/lib/docker/volumes/1522d54c954c755250cb71686cacd9714cd3d0f0c706ec18c1e490c7881fe713/_data/docker/registry/v2
地址就是咱們掛載地址：
看一下相關標簽：
[root@youx-pub registry]# curl http://192.168.18.162:5000/v2/_catalog{"repositories":["youx-centos7.5.1804","youx-centos7.5.1804-v1.0"]}[root@youx-pub registry]# curl http://192.168.18.162:5000/v2/youx-centos7.5.1804-v1.0/tags/list{"name":"youx-centos7.5.1804-v1.0","tags":["latest"]}[root@youx-pub registry]#可以之后我們直接刪除：
[root@master registry]# delete_docker_registry_image --image youx-centos7.5.1804-v1.0:latest
INFO [2017-04-08 11:39:39,793] Deleting /registry/docker/registry/v2/repositories/nginx/_manifests/tags/v1
咱們再看一下本地倉庫的鏡像有幾個：
[root@master registry]# curl http://192.168.18.162:5000/v2/_catalog{"repositories":["youx-centos7.5.1804"]}以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持VEVB武林網。
