云计算
1.Docker登入docker hub账号，（Docker hub上申请的账号即可）
[root@www ~]# docker login Login with your Docker ID to push and pull images from Docker Hub. If you don't have a Docker ID, head over to https://hub.docker.com to create one. Username: ****** Password: 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
2.搜索镜像库中的镜像；
[root@www ~]# docker search nginx NAME DESCRIPTION STARS OFFICIAL AUTOMATED nginx Official build of Nginx. 10250 [OK] jwilder/nginx-proxy Automated Nginx reverse proxy for docker con… 1462 [OK] richarvey/nginx-php-fpm Container running Nginx + PHP-FPM capable of… 647 [OK] jrcs/letsencrypt-nginx-proxy-companion LetsEncrypt container to use with nginx as p… 438 [OK] kong Open-source Microservice & API Management la… 247 [OK] webdevops/php-nginx Nginx with PHP-FPM 117 [OK] kitematic/hello-world-nginx A light-weight nginx container that demonstr… 112 zabbix/zabbix-web-nginx-mysql Zabbix frontend based on Nginx web-server wi… 75 [OK] bitnami/nginx Bitnami nginx Docker Image 58 [OK] 1and1internet/ubuntu-16-nginx-php-phpmyadmin-Mysql-5 ubuntu-16-nginx-php-phpmyadmin-MYSQL-5 47 [OK] linuxserver/nginx An Nginx container, brought to you by LinuxS… 43 tobi312/rpi-nginx NGINX on Raspberry Pi / armhf 23 [OK] blacklabelops/nginx Dockerized Nginx Reverse Proxy Server. 12 [OK] nginx/nginx-ingress NGINX Ingress Controller for Kubernetes 12 wodby/drupal-nginx Nginx for Drupal container image 11 [OK] centos/nginx-18-centos7 Platform for running nginx 1.8 or building n… 8 nginxdemos/hello NGINX webserver that serves a simple page co… 8 [OK] centos/nginx-112-centos7 Platform for running nginx 1.12 or building … 5 1science/nginx Nginx Docker images that include Consul Temp… 4 [OK] travix/nginx NGinx reverse proxy 2 [OK] pebbletech/nginx-proxy nginx-proxy sets up a container running ngin… 2 [OK] mailu/nginx Mailu nginx frontend 2 [OK] toccoag/openshift-nginx Nginx reverse proxy for Nice running on same… 1 [OK] wodby/nginx Generic nginx 0 [OK] ansibleplaybookbundle/nginx-apb An APB to deploy NGINX 0 [OK]
3.docker拉取存在docker hub上的镜像至本地（下载Docker hub上的镜像）；
[root@www ~]# docker pull httpd:2.4.37-alpine 2.4.37-alpine: Pulling from library/httpd 4fe2ade4980c: Already exists 42101a4e4c4e: Pull complete 73eadb9961ff: Pull complete 830983fb5ec2: Pull complete 78fb51bbfc27: Pull complete Digest: sha256:b875793145fe613aa2d1f73f1cd8ec09b775abcd6980024bc60a6a9c73d644fc Status: Downloaded newer image for httpd:2.4.37-alpine [root@www ~]# docker image ls REPOSITORY TAG IMAGE ID CREATED SIZE httpd 2.4.37-alpine 11fc0c2a2dfa 4 days ago 91.8MB nginx 1.14-alpine 77bae8d00654 13 days ago 17.7MB ljymyy/nginx latest 77bae8d00654 13 days ago 17.7MB
4.基于容器制作镜像
[root@www ~]# docker container run --name httpd1 httpd:2.4.37-alpine AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 172.17.0.2. Set the 'ServerName' directive globally to suppress this message AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 172.17.0.2. Set the 'ServerName' directive globally to suppress this message [Tue Nov 20 09:19:04.710155 2018] [mpm_event:notice] [pid 1:tid 140394175941512] AH00489: Apache/2.4.37 (Unix) configured -- resuming normal operations [Tue Nov 20 09:19:04.719195 2018] [core:notice] [pid 1:tid 140394175941512] AH00094: Command line: 'httpd -D FOREGROUND'
[root@www ~]# docker exec -it httpd1 /bin/sh /usr/local/apache2 # /usr/local/apache2 # vi htdocs/index.html /usr/local/apache2 # exit [root@www ~]# docker commit httpd1 ljymyy/httpd:private sha256:0c28c4522c128a7dca17c26d2fd8eee4e57642b455c067832d5567da1128da5e [root@www ~]# docker image ls REPOSITORY TAG IMAGE ID CREATED SIZE ljymyy/httpd private 0c28c4522c12 6 seconds ago 91.8MB httpd 2.4.37-alpine 11fc0c2a2dfa 4 days ago 91.8MB nginx 1.14-alpine 77bae8d00654 13 days ago 17.7MB ljymyy/nginx latest 77bae8d00654 13 days ago 17.7MB [root@www ~]# curl 172.17.0.2 <html><body><h2>It works!</h2></body></html> test successful
测试：
[root@www ~]# docker run --name httpd2 --rm ljymyy/httpd:private AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 172.17.0.3. Set the 'ServerName' directive globally to suppress this message AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 172.17.0.3. Set the 'ServerName' directive globally to suppress this message [Tue Nov 20 09:39:27.805890 2018] [mpm_event:notice] [pid 1:tid 140674896550792] AH00489: Apache/2.4.37 (Unix) configured -- resuming normal operations [Tue Nov 20 09:39:27.806444 2018] [core:notice] [pid 1:tid 140674896550792] AH00094: Command line: 'httpd -D FOREGROUND' 172.17.0.1 - - [20/Nov/2018:09:39:39 +0000] "GET / HTTP/1.1" 200 63 [root@www ~]# curl 172.17.0.3 <html><body><h2>It works!</h2></body></html> test successful
5.为镜像打标签；（IMAGE ID为相同的）
[root@www ~]# docker tag ljymyy/httpd:private ljymyy/httpd:v2.0 [root@www ~]# docker image ls REPOSITORY TAG IMAGE ID CREATED SIZE ljymyy/httpd private 0c28c4522c12 5 minutes ago 91.8MB ljymyy/httpd v2.0 0c28c4522c12 5 minutes ago 91.8MB httpd 2.4.37-alpine 11fc0c2a2dfa 4 days ago 91.8MB ljymyy/nginx latest 77bae8d00654 13 days ago 17.7MB nginx 1.14-alpine 77bae8d00654 13 days ago 17.7MB
6.将本地镜像上传至docker hub库中；
在docker hub上的dashboard中创建一个个人的Repository；创建相对应的namespace和repository name；例如：ljymyy/httpd
[root@www ~]# docker push ljymyy/httpd:v2.0 The push refers to repository [docker.io/ljymyy/httpd] 9dd07a03f263: Layer already exists 86503dd49098: Layer already exists 9caa02067460: Layer already exists 05f824de9453: Layer already exists 7df053e22514: Layer already exists df64d3292fd6: Layer already exists v2.0: digest: sha256:5b3aea8b8ed49fc642f46282c8bfeabf023fcbde0635341401a37ba0778af2a3 size: 1569
7.将镜像导入至文件中和导出文件中的镜像至本地；
[root@www ~]# docker save -o test.file nginx:1.14-alpine [root@www ~]# docker load -q -i test.file Loaded image: nginx:1.14-alpine
8.显示容器的详细信息；
[root@www ~]# docker container ls
