Docker, how to copy all .ear folders?

Каляшов Григорий :

I have a following structure:

[test]:

• Dockerfile
• [Test1.ear]
• [Test2.ear]
• ...
• [TestN.ear]

I'm trying copy all ear folders to "config/apps" folder:

COPY *.ear config/apps/

Structure in container which is expected:

[config/apps]:

• [Test1.ear]
• [Test2.ear]
• ...
• [TestN.ear]

But in "config/apps" folder copies only the contents (.war, .jar) of .ear folders.

How to use the COPY in this case?

atline :

Maybe you can use .dockerignore to add only Test1.ear, Test2.ear, etc to build context, then use COPY . config/apps to meet your requirements:

.dockerignore:

*
!*.ear

Dockerfile:

FROM alpine

COPY . config/apps

Test:

cake@cake:~/1$ ls
abc  Dockerfile  Test1.ear  Test2.ear

cake@cake:~/1$ docker build -t abc:1 .
