Docker 问题汇总

1、本例是在 Jenkins 里面远程发布的机器上报错，这里用的 devops 这个账号

ssh [email protected] docker pull 10.3.0.203:5001/gateway-api-dev      

Error response from daemon: Get http://10.3.0.203:5001/v2/fms-base-service-local/manifests/latest: no basic auth credentials

解决方法：

先登陆到这个用户下，然后登陆仓库 docker login http://10.3.0.203:5001

2、docker 安装的 mysql 备份

docker exec mysql3308 bash -c 'exec mysqldump -uroot -p!root123 \
--set-gtid-purged=OFF nacos_config | gzip' > /opt/backup/mysql/nacos_$(date +%Y%m%d).sql.gz      

3、把普通用户 加入 docker

Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.40/containers/json: dial unix /var/run/docker.sock: connect: permission denied

# 加入 docker 组
gpasswd -a kenny docker

# 查看

[root@rm ~]# id kenny
uid=1001(kenny) gid=1001(kenny) groups=1001(kenny),994(docker)

[root@rm ~]# groups kenny
kenny : kenny docker      

4、docker 网络占用

# 删除容器
docker rm -f contract-generate-service

# 清理网络占用
docker network disconnect --force bridge contract-generate-service

# 查看
docker network inspect bridge      

# 设置开机自启
docker container update --restart=always  nacos

# 取消开机自启
docker container update --restart=no nacos
