[rootmartin-host ~]# docker info
Client: Docker Engine - CommunityVersion: 26.1.4Context: defaultDebug Mode: falsePlugins:buildx: Docker Buildx (Docker Inc.)Version: v0.14.1Path: /usr/libexec/docker/cli-plugins/docker-buildxcompose: Docker Compose (Docker Inc.)Version: v2.27.1Path: /usr/libexec/docker/cli-plugins/docker-composeServer:Containers: 1Running: 0Paused: 0Stopped: 1Images: 4Server Version: 26.1.4Storage Driver: overlay2二、Dockerfile定制镜像
1、Dockerfile使用流程
1.1 编写Dockerfile
[rootmartin-host testDockerfile]# ls
CentOS-Base.repo Dockerfile
[rootmartin-host testDockerfile]# cat Dockerfile
FROM centos:7COPY CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repoRUN yum install -y net-tools1.2、构建镜像
[rootmartin-host testDockerfile]# docker build -t centos:v1 ./ 1.3 创建容器测试镜像定制操作
[rootmartin-host testDockerfile]# docker image ls
REPOSITORY TAG IMAGE ID CREATED SIZE
centos v1 3e88e2fdb6df 56 seconds ago 461MB
redis latest 7614ae9453d1 2 years ago 113MB
centos 7 eeb6ee3f44bd 2 years ago 204MB
nginx 1.18 c2c45d506085 3 years ago 133MB[rootmartin-host testDockerfile]# docker run -tid --nametest1 centos:v1
949b757d2b35b4d115a88f69cc8f1d704b6e6fcd34a64d4ecbfc28422e7530aa[rootmartin-host testDockerfile]# docker exec -ti test1 bash
[root949b757d2b35 /]# ifconfig
eth0: flags4163UP,BROADCAST,RUNNING,MULTICAST mtu 1472inet 10.88.7.2 netmask 255.255.255.0 broadcast 10.88.7.255ether 02:42:0a:58:07:02 txqueuelen 0 (Ethernet)RX packets 8 bytes 656 (656.0 B)
2、Dockerfile常用指令
FROM 指定基础镜像 镜像不存在构建镜像时自动下载镜像 建议尽量选择小容量的镜像 / debian/ ubuntu
FROM 镜像名称 RUN 指定定制命令
RUN 命令 命令 命令CMD 定义容器创建时自动执行的命令 注意事项: 1、前台启动服务的指令 2、创建容器时不要自己指定命令会覆盖CMD 3、一个Dockerfile中只能有一条CMD指令
CMD httpd -D FOREGROUND
CMD [httpd, -D, FOREGROUND] // 推荐ENTRYPOINT 定义容器创建时自动执行的命令 不会被覆盖
ENTRYPOINT [httpd, -D, FOREGROUND]COPY 复制文件 注意只能复制本地文件
COPY 源文件 目的文件 ADD 复制文件 注意 1、支持本地文件、URL、压缩包会自动解压
ADD 源文件 目的文件 ADD file01 /tmp/file01
ADD http://nginx.org/download/nginx-1.27.0.tar.gz /tmp
ADD jdk-8u91-linux-x64.tar.gz /tmpEXPOSE 说明容器服务端口 注意 1、-P随机发布端口时Dockerfile中必须有EXPOSE指令
EXPOSE 端口 端口VOLUME 定义持久化存储的目录 创建容器时不使用-v明确指定目录会自动生成匿名卷
VOLUME 目录ENV 定义环境变量
ENV 变量名称 值 WORKDIR 定义当前目录
WORKDIR 目录USER 指定容器运行的用户
USER 用户名三、部署springcloud微服务架构的商品秒杀项目
1、部署项目需要的基础服务
