Support for Alpine Linux with only sh

[khanetor]

I was trying to use Alpine Linux base Docker image. However the container from the built image cannot start because the start script has a bash hashbang up top, and Alpine Linux does not come with bash by default. I can easily install bash to Alpine Linux, but I wonder if bash is necessary to run an SBT program or sh is more than enough.

Hi

Thanks for feature request. We already have a ash configuration plugin. I'm not sure if this is enough, but you could try or use it as an example on how to create your own Sh script ( and maybe provide it as a PR :) )

Actually I used the AshScriptPlugin and it looked working (Alpine includes ash).

schmitch@SHANGHAI:~/projects/schmitch/hansili$ docker run -ti -p 9092:9092 hansili:SNAPSHOT -Dhttp.port=9092
bin/hansili: line 45: is_cygwin: not found
bin/hansili: line 45: addJava: not found
[info] - application - Creating Pool for datasource 'default'
Oops, cannot start the server.

the failure is due to the database connection, but it actually started correctly. The base image was: java:openjdk-8u77-jre-alpine.

Yes. AshscriptPlugin works well :). Thanks

is it me, or does it seem like this plugin is no longer supported ?

[muuki88]

What concrete issue do you have? And to which plugin are you referring?

[ogirardot]

Well the Bash template of the JavaAppPackaging is not (obviously) compatible out of the box with ash of the alpine distribution. And I thought the plugin AshscriptPlugin referred to in this PR did not seem to exist anymore but with further research it seems its only available since the 1.2.0 which is not yet released right ?

[muuki88]

The AshScriptPlugin is available since 1.0.4. See the related tags in the initial commit.

In 1.2.x the plugin was moved in another package, but that doesn't have any user impact.
