使用dockerfile 從私有倉庫構建鏡像，並啓動一個jenkins

私有倉庫已經搭建好了，先講解下環境

個人docker registry在mesos slave 上，也就是以前的

能夠看到私有的倉庫裏面已經有了3個鏡像，此次咱們要使用jenkins這個鏡像，這個鏡像主要包含了JAVA環境和一個tomcat工程，工程的webapps下是沒有東西的

 

如今我在私有倉庫的機器上刪除全部的鏡像和容器

root@web2:/opt/dockerfiles# docker images 
REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE

root@web2:/opt/dockerfiles# docker ps -a
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

 

看看個人Dockerfile

root@web2:/opt/dockerfiles# pwd
/opt/dockerfiles
root@web2:/opt/dockerfiles# ls
Dockerfile  jenkins.war
root@web2:/opt/dockerfiles# more Dockerfile 
FROM 172.16.126.129/jenkins

開始構建鏡像

咱們構建一個REPOSITORY爲jenkins   tag爲test的鏡像

OK，已經構建好了，如今開始啓動容器

已經成功啓動

使用WEB測試
