关于这个问题

查看是否安装 Podman
rpm -q podman
podman-1.4.2-5.module_el8.1.0+237+63e26edc.x86_64
删除Podman
dnf remove podman
还有一个buildah
也是这样的操作
查看是否安装 buildah
rpm -q buildah
删除buildah
dnf remove buildah

 

 

未找到容器：容器启动失败

 

 

把dataease的数据配置改为内部数据库重新离线安装，后

 

 

启动 Docker

sudo systemctl start docker
1
拉取容器

docker pull redis:latest
1
Docker 命令
镜像
docker images 查看容器
docker rmi [镜像id] 删除镜像
docker rmi redis
容器
docker ps 查看启动镜像
docker ps -a 查看所有镜像
docker start [容器id/容器别名] 启动容器
docker start nginx-2
docker stop [容器id/容器别名] 停止容器
docker stop nginx-2
docker restart [容器id/容器别名] 重启容器
docker restart nginx-2
docker exec -it [容器id/容器别名]:TAG /bin/bash 进入容器
docker exec -it nginx-2 /bin/bash
docker rm -f [容器id/容器别名] 删除容器
docker rm -f nginx-2
docker run -d -p :启动容器
-d 表示后台运行 -p 表示端口映射
docker port 查看容器端口映射信息
docker port nginx-2
docker logs 查看容器日志信息
docker logs nginx-2
docker top 查看容器运行的进程
docker top nginx-2
docker inspect 查看容器信息
- docker inspect nginx-2

docker 中不能用vim编辑文件
更新来源

apt-get update

安装vim

apt-get install -y vim

docker导入导出
导出：> 目录/文件名.tar
docker export nginx-2 > /nginx2.tar
注意：导入后通过docker images 查看

docker import nginx-test.tar nginx:imp
或者
cat nginx-test.tar | docker import - nginx:imp

开启远程访问权限
vi /lib/systemd/system/docker.service
#修改ExecStart这行
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock

#重新加载配置文件
# systemctl daemon-reload
#重启服务
# systemctl restart docker.service
#查看端口是否开启
# netstat -nlpt
#直接curl看是否生效
# curl http://127.0.0.1:2375/info

Linux系统检查端口是否开放
方法一
查看想开的端口是否已开：
firewall-cmd --query-port=2375/tcp

添加指定需要开放的端口：
firewall-cmd --add-port=2375/tcp --permanent

重载入添加的端口：
firewall-cmd --reload

查询指定端口是否开启成功：
firewall-cmd --query-port=123/tcp

移除指定端口：
firewall-cmd --permanent --remove-port=123/tcp

方法二
安装iptables-services ：
yum install iptables-services
进入下面目录进行修改：
/etc/sysconfig/iptables
