使用Docker遇到的各种问题_docker镜像部署之后 invli host header

目录

Docker镜像下载慢

如何在Docker容器中使用docker命令

Docker刚安装后执行docker ps -a报错（centos）

Dockerfile中用pip install命令一直retry，容器中pip确是可以下载的

Docker镜像下载慢

需要更改一下默认的下载地址

cd /etc/docker

配置镜像位置

vim daemon.json
{
    "registry-mirrors":["https://almtd3fa.mirror.aliyuncs.com"]      
}

重启docker

systemctl daemon-reload && systemctl restart docker

如何在Docker容器中使用docker命令

在启动docker容器的时候挂载以下两个目录

-v /usr/bin/docker:/usr/bin/docker
-v /var/run/docker.sock:/var/run/docker.sock

Docker刚安装后执行docker ps -a报错（centos）

通过yum install -y docker安装docker后，执行docker ps -a检查一下是否docker已运行。

[root@localhost]# docker ps -a
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

这个情况是没有运行docker导致的。。。所以启动一下docker就可以。

[root@localhost]# docker ps -a
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
[root@localhost]# systemctl start docker
[root@localhost]# docker ps -a

[root@localhost]# systemctl enable docker

可能是docker的dns问题，在daemon.json中增加dns后重启下docker

vim /etc/docker/daemon.json
{
    "registry-mirrors":["https://almtd3fa.mirror.aliyuncs.com"],
    "dns": ["114.114.114.114", "8.8.8.8"]     
}
 
 
service docker restart

执行docker exec后 报错http: invalid Host header

在某OS的docker 18的版本上发生这样的错，手动更新docker至24.0.5版本后解决
