Docker常见错误

一、存储驱动错误

问题：

[root@xiaoqiang docker]# docker run hello-world
docker: Error response from daemon: error creating aufs mount to /var/lib/docker/aufs/mnt/9f1cc4ec95241a1432a23f4ee7a1eb1c3fcf239ad203f915668967685ded08c4-init: invalid argument.
See 'docker run --help'.

解决：

# 修改存储类型
vim /etc/docker/daemon.json
{
  "storage-driver": "vfs",
  "registry-mirrors": ["https://v8o5rqy6.mirror.aliyuncs.com"]
}
# 重启docker服务
systemctl daemon-reload && systemctl restart docker

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

# 存储类型有
|Storage driver |Must match backing filesystem |
|---------------|------------------------------|
|overlay        |No                            |
|aufs           |No                            |
|btrfs          |Yes                           |
|devicemapper   |No                            |
|vfs            |No                            |
|zfs            |Yes                           |

二、启动权限不够

问题：

operation not permitted

[root@xiaoqiang nacos]# ls
data  docker-compose.yaml
[root@xiaoqiang nacos]# docker-compose up
Starting nacos ... error

ERROR: for nacos  Cannot start service nacos: OCI runtime create failed: container_linux.go:348: starting container process caused "operation not permitted": unknown

ERROR: for nacos  Cannot start service nacos: OCI runtime create failed: container_linux.go:348: starting container process caused "operation not permitted": unknown
ERROR: Encountered errors while bringing up the project.

解决：

去掉privileged或者加上privileged

三、服务启动超时

问题：

root@xiaoqiangzai:/home/qiang/docker-compose/nacos[root@xiaoqiangzai nacos]# docker-compose up -d && docker logs -f nacos
Creating network "nacos_default" with the default driver
Creating nacos ... 

ERROR: for nacos  UnixHTTPConnectionPool(host='localhost', port=None): Read timed out. (read timeout=60)

ERROR: for nacos  UnixHTTPConnectionPool(host='localhost', port=None): Read timed out. (read timeout=60)
ERROR: An HTTP request took too long to complete. Retry with --verbose to obtain debug information.
If you encounter this issue regularly because of slow network conditions, consider setting COMPOSE_HTTP_TIMEOUT to a higher value (current value: 60).

解决：

vim /etc/profile
export COMPOSE_HTTP_TIMEOUT=500
export DOCKER_CLIENT_TIMEOUT=500
source /etc/profile

四、登录界面重叠

问题：

引起这个问题的原因是在使用"docker run"运行容器时使用了 “/sbin/init"和”–privileged"参数。使用/sbin/init启动容器并加上–privileged参数，相当于docker容器获得了宿主机的全权委托权限。这时docker容器内部的init与宿主机的init产生了混淆。

解决：

systemctl status getty@tty1.service
systemctl stop getty@tty1.service
systemctl disable getty@tty1.service
