Re: Node.js agent wont connect to controller

Hi Sayak,

 

It looks like all this needs is the bash shell installed in the container. If you amend your Dockerfile changing this line:

apk --allow-untrusted add glibc-bin-2.25-r0.apk glibc-2.25-r0.apk curl && \

to this:

apk --allow-untrusted add glibc-bin-2.25-r0.apk glibc-2.25-r0.apk curl bash && \

All should work.

 

Please let me know how it goes.

 

Regards,

Kyle

Re: Node.js agent wont connect to controller

Thank you Kyle! I am facing some other challenges with my base image (I was not using mhart/alpine-node before – and I am facing issues if I use it).
Let me temporarily switch back to mhart/alpine-node and try this out.

Re: Node.js agent wont connect to controller

Hi Kyle,

 

It still isn't able to connect to proxy. However, i am able to curl the saas controller from within the container.

Also, pl notice the crypto error in the stacktrace.
