#docker命令
#查看运行中的容器
docker ps
#查看所有容器包含非运行状态的
docker ps -a
#搜索镜像
docker search nginx
#下载镜像
docker pull nginx
#下载指定版本镜像
docker pull nginx:1.26.0
#查看所有本地镜像
docker images
#删除指定id的镜像
docker rmi e784f4560448#运行一个新容器以nginx为例
docker run nginx
#停止容器
docker stop nginx
#启动容器以容器ID592为例容器ID用docker ps命令查看
docker start 592
#重启容器以容器ID592为例容器ID用docker ps命令查看
docker restart 592
#查看容器资源占用情况以容器ID592为例容器ID用docker ps命令查看
docker stats 592
#查看容器日志以容器ID592为例容器ID用docker ps命令查看
docker logs 592
#删除指定容器以容器ID592为例容器ID用docker ps命令查看
docker rm 592
#强制删除指定容器以容器ID592为例容器ID用docker ps命令查看
docker rm -f 592
# 后台启动容器-d
docker run -d --name mynginx nginx
# 后台启动并暴露端口-p
docker run -d --name mynginx -p 80:80 nginx
# 进入容器内部exec命令
docker exec -it mynginx /bin/bash# 提交容器变化打成一个新的镜像
docker commit -m update index.html mynginx mynginx:v1.0
# 保存镜像为指定文件
docker save -o mynginx.tar mynginx:v1.0
# 删除多个镜像
docker rmi bde7d154a67f 94543a6c1aef e784f4560448
# 加载镜像
docker load -i mynginx.tar # 登录 docker hub
docker login
# 重新给镜像打标签
docker tag mynginx:v1.0 leifengyang/mynginx:v1.0
# 推送镜像
docker push leifengyang/mynginx:v1.0# 查看分卷列表
Docker volume ls# 查看卷详情
docker volume inspect [volume name]
# 创建一个网络使用自定义的网络可以实现docker之间通过名称访问
Docker network create mynet
# 列举网络
Docker network ls3. 存储
两种方式注意区分命令都是“-v”以目录开头的是目录挂载此方式以外部目录为主覆盖容器目录 以变量开头的方式为卷映射以容器内部为主在宿主机的/var/lib/docker/volumes/目录下会新建卷来映射容器中的指定位置
• 目录挂载 -v /app/nghtml:/usr/share/nginx/html • 卷映射-v ngconf:/etc/nginx
# 命令示例
docker run -d -p 80:80 \
-v /app/nghtml:/usr/share/nginx/html \
-v ngconf:/etc/nginx \
--name app03 \
nginx配置文件可以使用卷映射以容器为主 数据目录可以使用挂载盘以宿主机为主
4. 网络
虽然docker官方只带网络“docker0”但是默认网络不支持使用域名访问一般我们需要自定义一个网络然后让相关的容器都加入这个网络实现容器间域名访问注意容器间网络交互使用容器内部端口而非宿主机映射端口。
# 创建一个网络使用自定义的网络可以实现docker之间通过名称访问
Docker network create mynet
# 列举网络
Docker network ls
# 让容器加入mynet网络
docker run -d -p 80:80 \
-v /app/nghtml:/usr/share/nginx/html \
-v ngconf:/etc/nginx \
--name mynginx \
--network mynet \
nginx5. redis主从复制示例
#自定义网络
docker network create mynet
#主节点
docker run -d -p 6379:6379 \

wordpress7. DockerFile
利用Dockerfile将自己的jar包打包成镜像以app.jar为例
vim Dockerfile
# 输入以下内容
FROM openjdk:17
LABEL authorguailiwugui
COPY app.jar /app.jar
EXPOSE 8080
ENTRYPOINT [java,-jar,/app.jar]# esc wq 保存并退出
# 构建镜像(最后一个.表示指定目录为当前目录)
docker build -f Dockerfile -t myapp:v1.0 .8. 一键安装超多中间件compose
环境准备前置命令
#Disable memory paging and swapping performance
sudo swapoff -a# Edit the sysctl config file
sudo vi /etc/sysctl.conf# Add a line to define the desired value
# or change the value if the key exists,
# and then save your changes.
vm.max_map_count262144# Reload the kernel parameters using sysctl
sudo sysctl -p# Verify that the change was applied by checking the value
cat /proc/sys/vm/max_map_count注意 ● 将下面文件中 kafka 的 119.45.147.122 改为你自己的服务器IP。 ● 所有容器都做了时间同步这样容器的时间和linux主机的时间就一致了 准备一个 compose.yaml文件内容如下 name: devsoft
