My plugin will build and install, but kibana wont run

Elastic Stack Kibana
1

I'm developing a plugin with Kibana v7.5.1, and I have it in a state where I want to build the plugin and install it into a docker container, and recommit the container and save it to my private registry.
All of these steps works just fine

yarn kbn bootstrap
yarn start  # for development
yarn build

builds just fine, then trying to install and run, the following steps are actually in a Dockerfile, but behave the same done this way.

docker run --rm -it --name kb docker.elastic.co/kibana/kibana:7.5.1 bash

In another shell:

docker cp /path/to/built/plugin.zip kb:/plugin.zip

back in kibana container

bin/kibana-plugin install file:///plugin.zip
... # installs just fine
bin/kibana

the bin/kibana command will give me the following output:
FATAL Error: Cannot find module '/usr/share/kibana/plugins/myPlugin'

plugins/myPlugin exists, and has my code in it. Why cant it be found?

Hi, it looks to me like you're using the right steps to make this Docker image.

  • Have you tried running your plugin in "dist" mode before this? Instead of yarn start give this a try: node scripts/kibana --config=config/kibana.dev.yml and see if Kibana can run with your plugin in non-dev mode.

  • Can you include more of the error message? I want to see if there is a stack trace that is pointing to the problem

So when I run the container, the follow log gets dumped:

Error: Cannot find module '/usr/share/kibana/plugins/cadence'

Followed by a couple lines saying its stopping other (builtin) plugins, then by:

 FATAL  Error: Cannot find module '/usr/share/kibana/plugins/cadence'

For running the node scripts/kibana --config path/to/config, Everything starts fine. Browsing to my.kibana.url.com/status shows my plugin is GREEN

I'm sorry but I'm really not sure what's going wrong. It's hard to say without access to the code.

Just a wild guess, but there is an index.js file in this path, correct? One thing to check is that Typescript conversion is happening properly, if that's applicable.

5

Actually, yeah. Thanks for pointing that out. I am using typescript everywhere, including the index.ts. When I unpack the .zip, there is no index.js next to the node_modules.

All other files in the server code is correctly compiled down from typescript to js.

I just checked, and if I change index.ts to index.js, index.js will now be in the package after I build it.

After installing, it looks like Kibana will run, but I do not see my plugin at the moment. I'll continue investigating later today.

So changing index.ts to index.js has the plugin working now. This looks like a bug, and I'll make an issue on the kibana repo.

I'm glad to hear we figured it out! Thanks for filing the bug for tracking
