1. 鏡像存儲(chǔ)規(guī)劃

• linux LVM /dev/sdb mount dir /data【linux LVM 磁盤掛載目錄】

創(chuàng)建兩個(gè)目錄

• 一個(gè) docker 數(shù)據(jù)存儲(chǔ)目錄 ：/data/docker，默認(rèn)一般為linux為 /var/lib/docker，windows 為C:\ProgramData\docker
• 一個(gè)registry 鏡像倉(cāng)庫(kù)數(shù)據(jù)目錄： /data/registry

mkdir /data/docker
mkdir /data/registry

2. 安裝定制 docker

• docker install 【docker 安裝】

yum install -y yum-utils 
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
yum list docker-ce --showduplicates | sort -r
sudo yum -y install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

配置

cat <<EOF> /etc/docker/daemon.json 
{"exec-opts": ["native.cgroupdriver=systemd"],"data-root": "/data/docker","live-restore": true,"log-driver": "json-file","log-opts": {"max-size":  "100m","max-file": "5"}}
EOF

啟動(dòng)

sudo systemctl start docker && systemctl enable docker  && systemctl status docker

驗(yàn)證

$ ls /data/docker/
buildkit  containers  engine-id  image  network  overlay2  plugins  runtimes  swarm  tmp  volumes

3. 部署 registry

拉取鏡像

docker pull registry:2.8.3

創(chuàng)建鏡像倉(cāng)庫(kù)

docker run -tid --restart=always --name registry -p 80:5000 -v /data/registry:/var/lib/registry registry:2.8.3

檢查狀態(tài)

$ docker ps
CONTAINER ID   IMAGE            COMMAND                  CREATED         STATUS         PORTS                                       NAMES
238a044893a5   registry:2.8.3   "/entrypoint.sh /etc…"   5 seconds ago   Up 4 seconds   0.0.0.0:80->5000/tcp, :::80->5000/tcp   registry

配置域名解析

echo "192.168.10.22  registry01.ghostwritten.com" >> /etc/hosts

修改配置

$ cat /etc/docker/daemon.json
{"exec-opts": ["native.cgroupdriver=systemd"],"insecure-registries": ["registry01.ghostwritten.com"],  #添加"data-root": "/data/docker","live-restore": true,"log-driver": "json-file","log-opts": {"max-size":  "100m","max-file": "5"}}$ systemctl restart docker

4. 驗(yàn)證鏡像倉(cāng)庫(kù)

檢查倉(cāng)庫(kù)

$ curl 192.168.10.22/v2/_catalog
{"repositories":[]}

推送鏡像

$ docker tag registry:2.8.3 registry01.ghostwritten.com/library/registry:2.8.3
$ docker push registry01.ghostwritten.com/library/registry:2.8.3
The push refers to repository [registry01.ghostwritten.com/library/registry]

拉取鏡像鏡像

登陸另一臺(tái)節(jié)點(diǎn)，重復(fù)上面安裝docker 、配置docker、配置域名解析，即可拉取鏡像

docker pull registry01.ghostwritten.com/library/registry:2.8.3
