docker registry 安裝

####docker registry

1.獲取docker registry鏡像

$ docker pull registry:2

Using default tag: latest
latest: Pulling from library/registry
b7f33cc0b48e: Pull complete
46730e1e05c9: Pull complete
458210699647: Pull complete
0cf045fea0fd: Pull complete
b78a03aa98b7: Pull complete
Digest: sha256:0e40793ad06ac099ba63b5a8fae7a83288e64b50fe2eafa2b59741de85fd3b97
Status: Downloaded newer image for registry:latest

2.運行docker registry

將本地/Users/JunGong/registry/data目錄掛在到容器/var/lib/registry目錄

$ docker run -d -p 5000:5000 --restart=always --name registry -v /Users/JunGong/registry/data:/var/lib/registry registry

使用https可以使用以下命令，須要ssl證書，或者前面在加層反向代理

$ docker run -d -p 5000:5000 --restart=always --name registry -v /Users/JunGong/registry/data:/var/lib/registry -v /Users/JunGong/registry/cert:/certs -e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/domain.crt -e REGISTRY_HTTP_TLS_KEY=/certs/domain.key registry

$ docker container ls

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
1502f1f6f7c1        registry            "/entrypoint.sh /e..."   15 seconds ago      Up 14 seconds       0.0.0.0:5000->5000/tcp   registry

3.推送image

push或pull images的時候會報錯，由於默認沒加證書，使用的http，可是默認須要使用https，須要在docker運行的時候加上 --insecure-registry 192.168.1.103:5000 參數啓動

$ docker images

REPOSITORY                 TAG                 IMAGE ID            CREATED             SIZE

registry                   latest              d1e32b95d8e8        3 weeks ago         33.2 MB
busybox                    latest              7968321274dc        3 weeks ago         1.11 MB

$ docker tag busybox 192.168.59.103:5000/mybusybox

$ docker push 192.168.59.103:5000/mybusybox

The push refers to a repository [192.168.59.103:5000/mybusybox]
