Docker啟動(dòng)報(bào)錯(cuò)"Job for docker.service failed because a configured resource limit was exceeded. See “systemctl status docker.service” and “journalctl -xe” for details."

配置docker跨主機(jī)集群之flannel之后第二天啟動(dòng)docker報(bào)錯(cuò)"Job for docker.service failed because a configured resource limit was exceeded. See “systemctl status docker.service” and “journalctl -xe” for details."

修改Docker啟動(dòng)參數(shù)

vim /lib/systemd/system/docker.service

配置docker跨主機(jī)集群時(shí)在docker的配置文件中作了修改

1.[Service]節(jié)中,指定啟動(dòng)參數(shù)所在的文件位置(這個(gè)配置是新增的)
EnvironmentFile=/run/flannel/docker_opts.env
2. 在原有ExecStart后面添加$DOCKER_OPTS
修改前
ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock
2.修改后
ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock $DOCKER_OPTS
將這兩個(gè)配置刪除，運(yùn)行systemctl daemon-reload后啟動(dòng)docker

daemon.json

vim /etc/docker/daemon.json

{"registry-mirrors":["https://ykxoezox.mirror.aliyuncs.com"]}

也有可能是daemon.json文件的格式問(wèn)題（多個(gè)逗號(hào)或者少個(gè)]）

卸載重裝

運(yùn)行卸載docker命令后，運(yùn)行yum list installed | grep docker查看是否有殘余

若還是解決不了，可參考https://blog.csdn.net/m0_46191508/article/details/107459939
