求解救：使用 docker 啟動 jenkins 遇到的問題。

漸漸發表於2020-07-16
DockerJenkins

執行命令：

sudo docker run --name qiuqiujenkins -p 8080:8080 -p 50000:50000 docker.io/jenkins/jenkins

如下報錯1，嘗試了各種網上搜尋，百度谷歌，也查了，並沒有什麼地方埠占用了，不知道是不是因為自己找的宿主機的沒有佔用，是不是docker裡的50000埠被佔用了？在解決過程中，又嘗試了幾次，沒有了報錯1 ，但是又來了報錯2，簡直絕望~~

# 報錯1
/usr/bin/docker-current: Error response from daemon: driver failed programming external connectivity on endpoint qiuqiujenkins (1c1a7148ea2078f9db5c74cc9b2ec720506c046dbdfb62429b2a227a7ef1de98): Bind for 0.0.0.0:50000 failed: port is already allocated.
ERRO[0000] error getting events from daemon: net/http: request canceled
# 報錯2
/usr/bin/docker-current: Error response from daemon: failed to update store for object type *libnetwork.endpointCnt: Key not found in store.
ERRO[0000] error getting events from daemon: net/http: request canceled

後續嘗試重啟docker

▶ sudo service docker start
Redirecting to /bin/systemctl start docker.service
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

▶ systemctl status docker.service
