為什么要使用https協議
因為不用 https 協議的話,docker 客戶端需要修改配置,如果 docker 客戶端多的話配置起來就很麻煩。
版本信息
- OS:
CentOS Linux 7.6 Release
- Docker:
18.09.6
- Docker-compose:
1.24.1
- Harbor:
harbor-offline-installer-v1.9.0
- IP:
172.0.0.11
1. 安裝 docker
1.1 配置 repository:
yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
1.2 安裝最新版本 docker-ce
yum install -y docker-ce
1.3 配置docker加速
- 參考docker.hub:https://www.daocloud.io/mirror
curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://f1361db2.m.daocloud.io
systemctl restart docker.service
1.4 啟動docker:
systemctl start docker
systemctl enable docker
2. 安裝 docker-compose
2.1 下載二進制文件
curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
- 如果需要安裝其他版本的話,請修改上面命令中的版本號。
2.2 賦予二進制文件可執行權限
chmod +x /usr/local/bin/docker-compose
ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
2.3 根據自己的情況決定是否安裝命令補全功能
yum install -y bash-completion
curl -L https://raw.githubusercontent.com/docker/compose/1.24.1/contrib/completion/bash/docker-compose -o /etc/bash_completion.d/docker-compose
2.4 測試是否安裝成功
docker-compose --version
3. harbor 開啟 https
- 如果使用 1.8 或者 1.9 版本,切記配置文件中 https 需要頂格,證書和 port 需要縮進相同單位,不然會報錯。
3.1 創建 ca 證書
mkdir -p /data/cert
cd /data/cert
3.2 生成 CA 的 key
cd /data/cert
openssl genrsa -out ca.key 4096
3.3 生成 CA 的 crt
cd /data/cert
openssl req -x509 -new -nodes -sha512 -days 3650 \
-subj "/C=CN/ST=Beijing/L=Beijing/O=chinatelecom/OU=ecloudcaas/CN=172.0.0.11" \
-key ca.key \
-out ca.crt
3.4 生成自己域名的 key
cd /data/cert
openssl genrsa -out 172.0.0.11.key 4096
3.5 生成自己域名的 csr
cd /data/cert
openssl req -sha512 -new \
-subj "/C=CN/ST=Beijing/L=Beijing/O=chinatelecom/OU=ecloudcaas/CN=172.0.0.11" \
-key 172.0.0.11.key \
-out 172.0.0.11.csr
3.6 生成一個 openssl 命令需要的外部配置文件
主要是subjectAltName,這里寫的IP.1=yourip還可以寫DNS.1=yourdomainname
cd /data/cert
cat > v3.ext <<-EOF
authorityKeyIdentifier=keyid,issuer
basicConstraints=CA:FALSE
keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
extendedKeyUsage = serverAuth
subjectAltName = @alt_names
[alt_names]
IP=172.0.0.11
EOF
3.7 通過 ext 和 csr 生成 crt
cd /data/cert
openssl x509 -req -sha512 -days 3650 \
-extfile v3.ext \
-CA ca.crt -CAkey ca.key -CAcreateserial \
-in 172.0.0.11.csr \
-out 172.0.0.11.crt
3.8 將服務端的 crt 轉換成客戶端用的 cert
cd /data/cert
openssl x509 -inform PEM -in 172.0.0.11.crt -out 172.0.0.11.cert
3.9 將帶域名的 cert,key 和 ca.crt 拷貝到 docker client 所在主機的 /etc/docker/certs.d/yourdomain/ 目錄下
mkdir -p /etc/docker/cert/172.0.0.11
cp /data/cert/172.0.0.11.cert /etc/docker/cert/172.0.0.11/
cp /data/cert/172.0.0.11.key /etc/docker/cert/172.0.0.11/
cp /data/cert/ca.crt /etc/docker/cert/172.0.0.11/
3.10 創建 /etc/docker/daemon
cat > /etc/docker/daemon.json << EOF
{ "insecure-registries":["http://172.0.0.11"] }
EOF
3.11 重啟 docker
systemctl daemon-reload
systemctl restart docker
4. 安裝 Harbor
4.1 下載 harbor 離線包
mkdir -p /home/harbor/
wget -P /home/harbor/ https://storage.googleapis.com/harbor-releases/release-1.9.0/harbor-offline-installer-v1.9.0.tgz
cd /home/harbor/
tar xf harbor-offline-installer-v1.9.0.tgz
cd /home/harbor/harbor
cp harbor.yml harbor.yml.bak
4.2 修改配置文件
- 其他地方不修改,只改以下幾處:
cd /home/harbor/harbor/
[root@harbor harbor]# egrep -v "^#|^$" harbor.yml|grep -v "#"
https:
port: 443
certificate: /home/harbor/cert/172.0.0.11.crt
private_key: /home/harbor/cert/172.0.0.11.key
4.3 更新參數
cd /home/harbor/harbor/
./prepare
4.4 安裝
cd /home/harbor/harbor/
./install
4.5 查看
Harbor
的日常運維管理是通過docker-compose
來完成的,Harbor
本身有多個服務進程,都放在docker
容器之中運行,可以通過docker ps
或者docker-compose
來查看:
cd /home/harbor/harbor/
[root@harbor harbor]# docker-compose ps

registry /entrypoint.sh /etc/regist ... Up (healthy) 5000/tcp

5. 網頁登錄和創建項目
- 在瀏覽器輸入:
https://172.0.0.11
; - 默認賬號密碼:
admin / Harbor12345
; - 創建一個項目:
os
;
6. 鏡像的推送
6.1 下載官方的 centos 鏡像
docker pull centos:7.4.1708
6.2 修改 TAG
docker tag centos:7.4.1708 172.0.0.11/os/centos:7.4.1708
docker images | grep centos
172.0.0.11/os/centos 7.4.1708 3afd47092a0e 2 months ago 197MB
centos 7.4.1708 3afd47092a0e 2 months ago 197MB
6.3 命令行登錄 harbor
cat > /etc/docker/daemon.json << EOF
{ "insecure-registries":["http://172.0.0.11"] }
EOF
systemctl daemon-reload
systemctl restart docker
[root@harbor harbor]# docker login 172.0.0.11
Username: admin
Password: Harbor12345
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store
Login Succeeded
6.4 推送鏡像到harbor(需要login)
docker push 172.0.0.11/os/centos:7.4.1708
6.5 在 harbor 中查看
7. 鏡像的拉取
- 假設是一台沒有登錄此 harbor 的 docker 客戶端
7.1 創建 /etc/docker/daemon.json 文件
{
"registry-mirrors": ["https:mirror.ccs.tencentyun.com","https://kuamavit.mirror.aliyuncs.com", "https://registry.docker-cn.com", "https://docker.mirrors.ustc.edu.cn"],
"insecure-registries" : ["http://172.0.0.11"],
"max-concurrent-downloads": 10,
"log-driver": "json-file",
"log-level": "warn",
"log-opts": {
"max-size": "10m",
"max-file": "3"
}
}
7.2 重啟 Docker 生效
systemctl daemon-reload
systemctl restart docker
7.3 拉取 harbor 中的鏡像
docker login 172.0.0.11
docker pull 172.0.0.11/os/centos:7.4.1708
