Is there a recommended base Docker image for a NodeJS app?

[Steven.Lira]

Is there an official recommendation for a base Docker image running NodeJs?  We are trying to instrument a NodeJS application using an Alpine-based Docker image (node:carbon-alpine) and ran into problems launching the proxy.  I've been trying to set it up as proxyless (libagent:true) but now I'm running into logging errors.  I started thinking that perhaps we should switch to a different base image.  Below is the logging error in case anyone has seen this before...

Hi Steven,

I guess you are trying to install the nodejs agent through npm? In case of alpine, you have to download the agent binaries from our download zone -

https://download.appdynamics.com/download/#version=&apm=nodejs&os=&platform_admin_os=&events=&eum=&p...

Let me know if this helps.

Also as an alternative you can also try node-slim​ docker image if you wish to use npm for agent installation.

Thanks

Hi Abhimanyu,

  You are correct - I am trying to install 4.5.4 using npm. I tried switching to carbon-slim and got the same error.  I removed libagent config and tried again and got a new error: 

Appdynamics agent cannot be initialized due to Error: /development/docker/app/node_modules/appdynamics-protobuf/protobuf_for_node.node: invalid ELF header

I will try the download and give it a shot...

How do you install the file downloaded from AppD downloads section? Are there any instructions?
