Docker常見錯誤

一、存儲驅動錯誤

問題：

[[email protected] 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'.
           

解決：

# 修改存儲類型
vim /etc/docker/daemon.json
{
  "storage-driver": "vfs",
  "registry-mirrors": ["https://v8o5rqy6.mirror.aliyuncs.com"]
}
# 重新開機docker服務
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

# 存儲類型有
|Storage driver |Must match backing filesystem |
|---------------|------------------------------|
|overlay        |No                            |
|aufs           |No                            |
|btrfs          |Yes                           |
|devicemapper   |No                            |
|vfs            |No                            |
|zfs            |Yes                           |
           

二、啟動權限不夠

問題：

operation not permitted
           

[[email protected] nacos]# ls
data  docker-compose.yaml
[[email protected] 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.

           

解決：

去掉privileged或者加上privileged
           

三、服務啟動逾時

問題：

[email protected]:/home/qiang/docker-compose/nacos[[email protected] 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).
           

解決：

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

四、登入界面重疊

問題：

引起這個問題的原因是在使用"docker run"運作容器時使用了 “/sbin/init"和”–privileged"參數。使用/sbin/init啟動容器并加上–privileged參數，相當于docker容器獲得了主控端的全權委托權限。這時docker容器内部的init與主控端的init産生了混淆。

解決：

systemctl status [email protected].service
systemctl stop [email protected].service
systemctl disable [email protected].service
