1、創建registry服務器

（1）安裝需要的包

<code>yum -y install podman httpd-tools/<code>

（2）創建registry目錄

<code>mkdir -p /opt/registry/{auth,certs,data}/<code>

（3）生成registry服務器證書 注意文件名不能更改改成其他名字，registry pod啟動時會找不到

<code>cd /opt/registry/certsopenssl req -newkey rsa:4096 -nodes -sha256 -keyout domain.key -x509 -days 365 -out domain.crt/<code>

（4）生成bcrpt格式的密碼

<code>htpasswd -bBc /opt/registry/auth/htpasswd root Scwang18/<code>

（5）創建mirror-registry容器

<code>podman run --name mirror-registry -p 5000:5000 \\     -v /opt/registry/data:/var/lib/registry:z \\     -v /opt/registry/auth:/auth:z \\     -e "REGISTRY_AUTH=htpasswd" \\     -e "REGISTRY_AUTH_HTPASSWD_REALM=Registry Realm" \\     -e REGISTRY_AUTH_HTPASSWD_PATH=/auth/htpasswd \\     -v /opt/registry/certs:/certs:z \\     -e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/domain.crt \\     -e REGISTRY_HTTP_TLS_KEY=/certs/domain.key \\     -d docker.io/library/registry:2/<code>

（6）添加防火牆端口

<code>firewall-cmd --add-port=5000/tcp --zone=internal --permanent firewall-cmd --add-port=5000/tcp --zone=public   --permanent firewall-cmd --reload/<code>

（7）添加簽名簽名證書到受信證書列表

<code>cp /opt/registry/certs/domain.crt /etc/pki/ca-trust/source/anchors/update-ca-trust/<code>

（8）測試registry是否可用

<code>curl -u root:xxxx -k https://registry.ipincloud.com:5000/v2/_catalog/<code>

2、修改pullsecret

在受限網絡安裝OCP，需要將私有鏡像registry的相關信息更新到pullsecret。

（1）從https://cloud.redhat.com/openshift/install/pull-secret下載pullsecret

<code>cat << 'EOF' > /opt/registry/certs/pull-secret.txt{"auths":{"cloud.openshift.com":{省略}}}EOF/<code> 

（2）將1步創建registry服務時使用的用戶名\\密碼轉換成base64編碼的token

<code>[root@misc certs]# echo -n 'root:Scwang18' | base64 -w0cm9vdDpTY3dhbmcxOA==[root@misc certs]#/<code>

（3）將pullsecret格式轉換成json，便於增加自己的私有registrt

<code>cat ./pull-secret.txt | jq .  > ./pull-secret.json/<code>

（4）將私有mirror registry添加到pull-secret.json

<code>[root@misc certs]# cat pull-secret.json{  "auths": {    "cloud.openshift.com": {            "auth": "省略",      "email": "省略"    },    "quay.io": {            "auth": "省略",      "email": "省略"    },    "registry.connect.redhat.com": {      "auth": "省略",      "email": "省略"    },    "registry.redhat.io": {      "auth": "省略",      "email": "[email protected]"    },    "registry.ipincloud.com:5000": {      "auth": "cm9vdDpTY3dhbmcxOA==",      "email": "[email protected]"    }  }}[root@misc certs]#/<code>

3、同步ocp鏡像倉庫到私有registry

（1）設置registry環境變量

<code>export OCP_RELEASE=4.3.0export LOCAL_REGISTRY='registry.ipincloud.com:5000' export LOCAL_REPOSITORY='ocp4/openshift4' export PRODUCT_REPO='openshift-release-dev' export LOCAL_SECRET_JSON='/opt/registry/certs/pull-secret.json' export RELEASE_NAME="ocp-release" /<code>

（2）開始鏡像

<code>oc adm release mirror -a ${LOCAL_SECRET_JSON} \\     --from=quay.io/${PRODUCT_REPO}/${RELEASE_NAME}:${OCP_RELEASE}-x86_64 \\     --to=${LOCAL_REGISTRY}/${LOCAL_REPOSITORY} \\     --to-release-image=${LOCAL_REGISTRY}/${LOCAL_REPOSITORY}:${OCP_RELEASE}     oc adm release mirror -a /opt/registry/certs/pull-secret.json --from=quay.io/openshift-release-dev/ocp-release:4.3.0-x86_64 --to-release-image=registry.ipincloud.com:5000/ocp4/openshift4:4.3.0 --to=registry.ipincloud.com:5000/ocp4/openshift4     /<code>

（3）同步完成後，記錄完成信息，在集群中使用
