自建docker仓库
作者：互联网
一、仓库安装
1、系统：CentOS7.9，采用yum安装方式
[root@master ~]# yum install docker-distribution -y ... ... [root@master ~]# rpm -ql docker-distribution /etc/docker-distribution/registry/config.yml /usr/bin/registry /usr/lib/systemd/system/docker-distribution.service /usr/share/doc/docker-distribution-2.6.2 /usr/share/doc/docker-distribution-2.6.2/AUTHORS /usr/share/doc/docker-distribution-2.6.2/CONTRIBUTING.md /usr/share/doc/docker-distribution-2.6.2/LICENSE /usr/share/doc/docker-distribution-2.6.2/MAINTAINERS /usr/share/doc/docker-distribution-2.6.2/README.md /var/lib/registry
[root@master ~]# systemctl start docker-distribution.service
[root@master ~]# systemctl enable docker-distribution.service
2、配置文件解读
vim /etc/docker-distribution/registry/config.yml
version: 0.1
log:
fields:
service: registry
storage:
cache:
layerinfo: inmemory
filesystem:
rootdirectory: /data/registry # 定义仓库镜像存储路径
http:
addr: 127.0.0.1:5000 # 定义监听端口
监听5000端口
3、nginx配置
upstream registry {
server 127.0.0.1:5000;
}
server {
listen 80;
server_name www.hello-word.vip hello-word.vip;
location / {
proxy_set_header Host $host;
proxy_pass http://registry;
}
access_log logs/access.log main;
error_log logs/error.log;
}
二、使用自建仓库
注意：以下操作均在树莓派4b上操作的，所以打出来的镜像只能用在arm64架构下；想在amd64架构下运行，需要将Dockerfile文件以及python文件复制到amd64架构的机器下打包；
1、准备Dockerfile文件和测试Python文件
Dockerfile
FROM alpine:3.9.5 RUN apk update && apk add --no-cache python3 net-tools COPY ["app.py","/tmp"] ENV HOST="localhost" ENV PORT="80" CMD python3 /tmp/app.py $HOST $PORT
测试Python文件
#!/usr/bin/env python3
#conding: utf-8
from http.server import HTTPServer, BaseHTTPRequestHandler
import json
import sys
import socket
def hostname():
return socket.gethostname()
def ipa():
return socket.gethostbyname(hostname())
data = {hostname(): ipa()}
def httpserver(ipadd='127.0.0.1',sport=8888):
host = (ipadd, sport)
server = HTTPServer(host, Resquest)
server.serve_forever()
class Resquest(BaseHTTPRequestHandler):
def do_GET(self):
self.send_response(200)
self.send_header('Content-type', 'application/json')
self.end_headers()
self.wfile.write(json.dumps(data).encode())
if len(sys.argv) == 1:
httpserver()
elif len(sys.argv) == 3:
httpserver(sys.argv[1],eval(sys.argv[2]))
2、构建镜像
root@raspberrypi:~/dockerfile/alpine # docker build -t alpine:arm-v0.1 ./ Sending build context to Docker daemon 3.584kB Step 1/6 : FROM alpine:3.9.5 3.9.5: Pulling from library/alpine eb93038481dd: Pull complete Digest: sha256:115731bab0862031b44766733890091c17924f9b7781b79997f5f163be262178 Status: Downloaded newer image for alpine:3.9.5 ... ... Successfully built 30068fd6c4af Successfully tagged alpine:arm-v0.1 root@raspberrypi:~/dockerfile/alpine # docker images REPOSITORY TAG IMAGE ID CREATED SIZE alpine arm-v0.1 30068fd6c4af About a minute ago 59.2MB
3、为镜像打tag
root@raspberrypi:~/dockerfile/alpine # docker tag alpine:arm-v0.1 hello-word.vip/alpine:arm64-v0.1
root@raspberrypi:~/dockerfile/alpine # docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
alpine arm-v0.1 30068fd6c4af 4 minutes ago 59.2MB
hello-word.vip/alpine arm64-v0.1 30068fd6c4af 4 minutes ago 59.2MB
4、修改docker的daemon.json配置文件
因为docker私有仓库服务默认是基于https传输的，而我的自建仓库是http的，所以需要配置不使用https传输；配置路径：/etc/docker/daemon.json
{
"exec-opts": ["native.cgroupdriver=systemd"],
"registry-mirrors": [
"https://docker.mirrors.ustc.edu.cn",
"https://registry.docker-cn.com",
"http://hub-mirror.c.163.com",
"https://mirror.ccs.tencentyun.com"
],
"insecure-registries": ["http://hello-word.vip"]
}
配置完daemon.json文件之后，需要重启docker服务，使配置文件生效；
5、上传镜像到私有仓库
root@raspberrypi:~/dockerfile/alpine # docker push hello-word.vip/alpine:arm64-v0.1 The push refers to repository [hello-word.vip/alpine] b0782aba8029: Pushed 5f6ff48124a4: Pushed a73aeeee9177: Pushed arm64-v0.1: digest: sha256:7de8ac1fb179c539e3c130d2c03196835af3a2eee51aa59ed75629c31a5d5d17 size: 947
三、自建仓库的常用操作
1、获取仓库镜像列表
root@pinode1:~ # curl -s http://hello-word.vip/v2/_catalog | jq
{
"repositories": [
"alpine",
"centos7/daemonapp",
"nginxdemos/hello",
"python-demo"
]
}
2、获取镜像的tag列表
root@pinode1:~ # curl -s http://hello-word.vip/v2/alpine/tags/list | jq
{
"name": "alpine",
"tags": [
"arm64-v0.1"
]
}
四、验证
1、下载镜像
root@raspberrypi:/home/pi/k8s # docker pull hello-word.vip/alpine:arm64-v0.1 arm64-v0.1: Pulling from alpine eb93038481dd: Already exists 1b4529d08552: Pull complete 43b89475a0ed: Pull complete Digest: sha256:7de8ac1fb179c539e3c130d2c03196835af3a2eee51aa59ed75629c31a5d5d17 Status: Downloaded newer image for hello-word.vip/alpine:arm64-v0.1 hello-word.vip/alpine:arm64-v0.1 root@raspberrypi:/home/pi/k8s # docker images REPOSITORY TAG IMAGE ID CREATED SIZE hello-word.vip/alpine arm64-v0.1 30068fd6c4af 3 hours ago 59.2MB
2、运行镜像测试
root@raspberrypi:/home/pi/k8s # docker run --rm --env HOST=0.0.0.0 --env PORT=8085 -p 8888:8085 hello-word.vip/alpine:arm64-v0.1
开启另一个终端，访问宿主机的8888端口，返回了镜像的hostname以及ip地址；测试成功
root@raspberrypi:~ # ss -ntl
State Recv-Q Send-Q Local Address:Port Peer Address:Port Process
LISTEN 0 128 0.0.0.0:22 0.0.0.0:*
LISTEN 0 4096 0.0.0.0:8888 0.0.0.0:*
... ...
root@raspberrypi:~ # curl 127.0.0.1:8888
{"8957ed456846": "172.17.0.2"}
