第2章 搭建私有registry

说明&＃xff1a;由于自己定制的镜像在官网没有&＃xff0c;并且docker有两台主机&＃xff0c;另一个主机要想用定制的镜像&＃xff0c;就需要搭建个docker仓库。
官方文档&＃xff1a;
https://docs.docker.com/registry/deploying/#run-an-externally-accessible-registry

Running a registry only accessible on localhost has limited usefulness. In order to make your registry accessible to external hosts, you must first secure it using TLS.

使用TLS认证registry容器时&＃xff0c;必须有证书。一般情况下&＃xff0c;是要去认证机构购买签名证书。这里使用openssl生成自签名的证书。

2.1 生成自签名证书

#选择一台docker服务器操作

mkdir -p /opt/docker/registry/certs
openssl req -newkey rsa:4096 -nodes -sha256 -keyout /opt/docker/registry/certs/domain.key -x509 -days 365 -out /opt/docker/registry/certs/domain.crt
Generating a 4096 bit RSA private key
...
Country Name (2 letter code) [XX]:CN
State or Province Name (full name) []:BeiJing
Locality Name (eg, city) [Default City] BeiJing
Organization Name (eg, company) [Default Company Ltd]:ceicloud
Organizational Unit Name (eg, section) []:edu
Common Name (eg, your name or your server&＃39;s hostname) []:registry.docker.com
Email Address []:zhaolidong&＃64;ceicloud.com


2.2 创建带有TLS认证的registry容器

docker run -d --name registry2 -p 443:443 -v /opt/docker/registry/certs:/certs -e REGISTRY_HTTP_ADDR&＃61;0.0.0.0:443 -e REGISTRY_HTTP_TLS_CERTIFICATE&＃61;/certs/domain.crt -e REGISTRY_HTTP_TLS_KEY&＃61;/certs/domain.key registry:2


2.3 在每一个docker客户端宿主机上配置/etc/hosts&＃xff0c;以使客户端宿主机可以解析域名”registry.docker.com”。并创建与这个registry服务器域名一致的目录&＃xff08;因为我这里的域名是假的&＃xff09;

#两台docker服务器都操作

vim /etc/hosts
172.16.206.32 registry.docker.com
cd /etc/docker/certs.d/
mkdir -p /etc/docker/certs.d/registry.docker.com:443


2.4 将证书 domain.crt 复制到每一个docker客户端宿主机

scp -p /opt/docker/registry/certs/domain.crt root&＃64;192.168.229.113:/etc/docker/certs.d/registry.docker.com\:443/ca.crt


#不需要重启docker

2.5 配置insecure_registry

证书不识别
The push refers to a repository [registry.docker.com/my-ubuntu]
Get https://registry.docker.com/v1/_ping: x509: certificate signed by unknown authority
解决

vim /etc/sysconfig/docker
OPTIONS&＃61;&＃39;--selinux-enabled&＃61;false --insecure-registry registry.docker.com:443&＃39;


还是报错&＃xff0c;将我们生成的crt文件内容放入系统的CA bundle文件当中&＃xff0c;使操作系统信任我们的自签名证书&＃xff0c;docker自然也就没问题了。CentOS 6 / 7中bundle文件的位置在

/etc/pki/tls/certs/ca-bundle.crt
cd /etc/docker/certs.d/registry.docker.com\:443/
cat ca.crt >>/etc/pki/tls/certs/ca-bundle.crt


重启docker

systemctl restart docker.service


#如果是其他Linux发行版&＃xff0c;该文件的位置可能是下面这些&＃xff0c;视情况而定&＃xff1a;

/etc/ssl/certs/ca-certificates.crt
/etc/ssl/ca-bundle.pem
/etc/ssl/cert.pem
/usr/local/share/certs/ca-root-nss.crt
/etc/init.d/docker restart


2.6 push镜像到registry

Docker客户端现在可以使用其外部地址从您的注册表中获取并推送到您的注册表。
docker pull ubuntu:16.04
docker tag ubuntu:16.04 registry.docker.com/my-ubuntu
docker push registry.docker.com/my-ubuntu
docker pull registry.docker.com /my-ubuntu

2.7 列出私有仓库中的所有镜像

curl -X GET https://registry.docker.com:443/v2/_catalog -k
{“repositories”:[“my-ubuntu”]}

2.8 查看存储在registry:2宿主机上的镜像

在registry:2创建的私有仓库中&＃xff0c;上传的镜像保存在容器的/var/lib/registry目录下。创建registry:2的容器时&＃xff0c;会自动创建一个数据卷(Data Volumes)&＃xff0c;数据卷对应的宿主机下的目录一般为&＃xff1a;/var/lib/docker/volumes/XXX/_data。

ls /var/lib/docker/volumes/91a0091963fa6d107dc988a60b61790bba843a115573e331db967921d5e83372/_data/docker/registry/v2/repositories/my-ubuntu/
_layers _manifests _uploads


可以在创建registry:2的容器时&＃xff0c;通过-v参数&＃xff0c;修改这种数据卷关系&＃xff1a;

–v /opt/docker/registry/data:/var/lib/registry


除了可以将数据保存在当前主机的文件系统上&＃xff0c;registry也支持其他基于云的存储系统&＃xff0c;比如S3&＃xff0c;Microsoft Azure, Ceph Rados, OpenStack Swift and Aliyun OSS等。可以在配置文件中进行配置&＃xff1a;https://github.com/docker/distribution/blob/master/docs/configuration.md#storage

第3章 创建overlay网络

3.1 搭建consul服务

wget https://releases.hashicorp.com/consul/1.3.0/consul_1.3.0_linux_amd64.zip
mv consul_1.3.0_linux_amd64.zip /opt/
cd /opt/
yum -y install unzip
unzip consul_1.3.0_linux_amd64.zip
mv consul /usr/bin/
consul agent -dev -ui -node&＃61;consul-dev -client&＃61;ip地址 2>&1 > /tmp/consul.log&


3.2 配置docker存储

vim /usr/lib/systemd/system/docker.service
[Service]
ExecStart&＃61;/usr/bin/dockerd -H fd:// --containerd&＃61;/run/containerd/containerd.sock --cluster-store&＃61;consul://consul主机的ip地址:8500 --cluster-advertise&＃61;节点的ip地址:2376
systemctl daemon-reload
systemctl restart docker
