Node.js agent wont connect to controller

[sayak.banerjee]

Hi everyone,

I have been trying to get the node.js agent (v4.3.6) to connect to our company's test SaaS controller from within an alpine linux (v3.4) docker container. I keep getting proxy errors (please see attached file).

Any ideas around how can I debug this issue?

Hi Sayak,

Could you provide your Dockerfile so that I can try and reproduce this?

Regards,

Kyle

I've tried to strip off any company internal code and attached what i have.

PS. Thank you so much for your help so far.

Hi Kyle,

Any luck with the issue? were you able to replicate it?

[Kyle.Furlong]

Hi Sayak,

I do apologize but I've had other committments. I will let you know as soon as I have more info to share.

Regards,

Kyle

No problem at all! Thank you for helping.

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

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.

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.
