Hey Sohrab-,
Believe you said in your blog that the 4.2.x runtime breaks this approach.
Are you still keen on using the org.mule.runtime.module.reboot.MuleContainerBootstrap class and running the container with a process signature almost identical to the stock MuleSoft approach?
Accepting PR's?

Cheers

Hi Sohrab ,

Thanks for the article .

I see the repo where this mule sample-app is basic app .

What i want to achieve is that I have spring boot application , which i want to run in mule runtime inside docker container?

I don't know is i am thinking right way . Can you tell me can we run java spring boot application in mule runtime.

Also why we need mule runtime app?

I know it silly question but i have read lot of block not able to clear

Hi Sohrab,

I was reproducing the tutorial (thanks for putting that content together!) and while building the images to deploy Mule on Openshift I realised that the repository link to OpenJDK's tree ends-up missing. I worked-around that by cloning the 'java' repository from fabric8io-images and replaced in the image repo. Thought of raising this issue to note that as well as to ask for a help on the RH subscription-manager related issue (at the end of the image build).

Have you seen this error before ?

Cheers,

Jose
