centos7搭建docker私有仓库
1.环境：
[root@docker02 anchors]# cat /etc/redhat-release CentOS Linux release 7.3.1611 (Core)
[root@docker02 anchors]# docker info Containers: 0 Running: 0 Paused: 0 Stopped: 0 Images: 3 Server Version: 17.03.1-ce
.....
10.60.10.39 docker01.lo -->仓库 10.60.10.40 docker02.lo -->客户端
10.60.10.41 docker03.lo -->客户端
2.仓库配置https认证
a.配置hosts文件
[root@docker01 ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
10.60.10.39 docker01.lo
10.60.10.40 docker02.lo
10.60.10.41 docker03.lo
b.生成证书
[root@docker01 ~]# cd /etc/docker/ [root@docker01 docker]# mkdir certs
#切到docker配置文件目录，新建certs目录。
[root@docker01 docker]# openssl req -newkey rsa:4096 -nodes -sha256 -keyout certs/docker01.lo.key -x509 -days 365 -out certs/docker01.lo.crt Generating a 4096 bit RSA private key ..........................................................................................................................................................................................................................................................................++ ..............++ writing new private key to ‘certs/docker01.lo.key‘ ----- You are about to be asked to enter information that will be incorporated into your certificate request. What you are about to enter is what is called a Distinguished Name or a DN. There are quite a few fields but you can leave some blank For some fields there will be a default value, If you enter ‘.‘, the field will be left blank. ----- Country Name (2 letter code) [XX]:CN State or Province Name (full name) []:ZJ Locality Name (eg, city) [Default City]:HZ Organization Name (eg, company) [Default Company Ltd]:ZX Organizational Unit Name (eg, section) []:ZX Common Name (eg, your name or your server‘s hostname) []:docker01.lo Email Address []:TEST@163.com
注意，以上红色字体的三处关键字要一致，这里我用得是仓库主机的主机名。
[root@docker01 docker]# ll certs/ total 8 -rw-r--r--. 1 root root 2049 Jun 19 14:41 docker01.lo.crt -rw-r--r--. 1 root root 3272 Jun 19 14:41 docker01.lo.key
3.运行registry容器
docker run -d -P -it -p 5000:5000 --restart=always --name registry_https01 -v `pwd`/certs:/etc/docker/certs/ -e REGISTRY_HTTP_TLS_CERTIFICATE=/etc/docker/certs/docker01.lo.crt -e REGISTRY_HTTP_TLS_KEY=/etc/docker/certs/docker01.lo.key registry
[root@docker01 docker]# docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 4b10b23f3dd0 registry "/entrypoint.sh /e..." 52 seconds ago Up 52 seconds 0.0.0.0:5000->5000/tcp registry_https01
[root@docker01 docker]# netstat -ntpl Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 852/sshd tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1559/master tcp6 0 0 :::22 :::* LISTEN 852/sshd tcp6 0 0 ::1:25 :::* LISTEN 1559/master tcp6 0 0 :::9022 :::* LISTEN 2154/dockerd tcp6 0 0 :::5000 :::* LISTEN 5545/docker-proxy tcp6 0 0 :::2377 :::* LISTEN 2154/dockerd tcp6 0 0 :::7946 :::* LISTEN 2154/dockerd
4.配置客户端（ 需要配置hosts文件如步骤2-a）
a.远程拷贝docker01.lo.crt到客户端/etc/pki/ca-trust/source/anchors目录下
[root@docker01 docker]# scp certs/docker01.lo.crt 10.60.10.40:/etc/pki/ca-trust/source/anchors root@10.60.10.40‘s password: docker01.lo.crt 100% 2049 2.0KB/s 00:00 [root@docker01 docker]# scp certs/docker01.lo.crt 10.60.10.41:/etc/pki/ca-trust/source/anchors root@10.60.10.41‘s password: docker01.lo.crt 100% 2049 2.0KB/s 00:00
b.更新证书
[root@docker02 ~]# cd /etc/pki/ca-trust/source/anchors
[root@docker02 anchors]# update-ca-trust
[root@docker03 ~]# cd /etc/pki/ca-trust/source/anchors
[root@docker03 anchors]# update-ca-trust
c.上传image

[root@docker03 anchors]# curl https://docker01.lo:5000/v2/_catalog {"repositories":["centos","ubuntu"]}
d.下载image
[root@docker02 anchors]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE nginx latest 958a7ae9e569 2 weeks ago 109 MB swarm latest 36b1e23becab 5 months ago 15.9 MB centos 6.8 0cd976dc0a98 9 months ago 195 MB docker01.lo:5000/centos 6.8 0cd976dc0a98 9 months ago 195 MB

5.问题解决：
[root@docker03 anchors]# docker push docker01.lo:5000/centos
The push refers to a repository [docker01.lo:5000/centos]
Get https://docker01.lo:5000/v1/_ping: x509: certificate signed by unknown authority
如碰到上述问题：
[root@docker03 anchors]# cat docker01.l.crt >> ca-bundle.crt [root@docker03 anchors]# update-ca-trust
[root@docker03 anchors]# systemctl restart docker
