docker
docker安装
centos安装docker,参见https://yeasy.gitbooks.io/docker_practice/content/install/centos.html
docker-compose安装
curl -L https://github.com/docker/compose/releases/download/1.25.0-rc2/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
harbor安装
安装之前确保前置条件是否满足，需要安装docker-compose、docker以及python2.7以上还有openssl
github-harbor安装指南:https://github.com/goharbor/harbor/blob/master/docs/installation_guide.md
harbor离线安装包,下载地址:https://storage.googleapis.com/harbor-releases/release-1.9.0/harbor-offline-installer-v1.9.0.tgz
解压下载的harbor安装包
tar -zxvf harbor-offline-installer-v1.9.0.tgz
配置harbor.yml
必要参数
修改如下参数后,需要重新执行install.sh重新安装才能生效
hostname:设置本机ip地址,访问harbor-ui界面使用,请勿使用localhost或127.0.0.1或0.0.0.0
data_volume:将harbor数据存储到宿主机的那个目录下
harbor_admin_password:初始化的harbor登录密码,default username/password are admin/Harbor12345
database：数据库相关的配置
password：启动后会创建一个harbor-db容器,里面的数据库密码
max_idle_conns：连接池中的最大空闲连接数。如果<= 0，则不保留任何空闲连接。默认值为50，如果未配 置，则默认值为2。
max_open_conns：最大连接数。如果<= 0，则打开的连接数没有限制。默认值为100。如果未配置，则值为 0。
jobservice：与jobservice相关的服务
max_job_workers：启动几个进程工作,小于cpu核心数吧
log: 相关配置,使用默认即可
harbor.yml
这里只修改hostname,其他默认即可

执行install.sh
出现如下信息,表示harbor安装成功,可以打开浏览器输入192.168.41.18,账户admin,密码上面配置的初始化密码
配置https访问
生成证书
openssl genrsa -out ca.key 4096
将下面出现的所有yourdomain.com改为harbor所在的服务器ip
openssl req -x509 -new -nodes -sha512 -days 3650 \
-subj "/C=CN/ST=Beijing/L=xicheng/O=zdjizhi/OU=Personal/CN=yourdomain.com" \
-key ca.key \
-out ca.crt
openssl genrsa -out yourdomain.com.key 4096
openssl req -sha512 -new \
-subj "/C=CN/ST=Beijing/L=xicheng/O=zdjizhi/OU=Personal/CN=yourdomain.com" \
-key yourdomain.com.key \
-out yourdomain.com.csr
cat > v3.ext <<-EOF
authorityKeyIdentifier=keyid,issuer
basicConstraints=CA:FALSE
keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
extendedKeyUsage = serverAuth
subjectAltName = @alt_names
[alt_names]
DNS.1=yourdomain.com
DNS.2=hostname
EOF
openssl x509 -req -sha512 -days 3650 \
-extfile v3.ext \
-CA ca.crt -CAkey ca.key -CAcreateserial \
-in yourdomain.com.csr \
-out yourdomain.com.crt
获取yourdomain.com.crt和yourdomain.com.key文件后，您可以将它们放入目录，例如/data/cert/
#harbor.yml中使用
cp 192.168.41.18.crt /data/cert/
cp 192.168.41.18.key /data/cert/
为Docker配置服务器证书，密钥和CA
openssl x509 -inform PEM -in yourdomain.com.crt -out yourdomain.com.cert
mkdir -p /etc/docker/certs.d/yourdomain.com/
cp yourdomain.com.cert /etc/docker/certs.d/yourdomain.com/
cp yourdomain.com.key /etc/docker/certs.d/yourdomain.com/
cp ca.crt /etc/docker/certs.d/yourdomain.com/
修改harbor.yml
添加
# https related config
https:
# https port for harbor, default is 443
port: 443
# The path of cert and key files for nginx
certificate: /data/cert/192.168.41.18.crt
