How to list plugins on a logstash docker container?

Elastic Stack Logstash
1

Logstash is running in a docker container, and I'd like to list its plugins.

For a VM or metal installation, Here is the command [Ref 1]

sudo bin/plugin list

How do I run this command in a Docker container? I've tried the following, but no luck: [Ref 3]

sudo docker exec -it docker-elk_logstash_1 plugin list
sudo docker exec -it docker-elk_logstash_1 bin/plugin list
sudo docker exec -it docker-elk_logstash_1 /bin/plugin list

Nope.

EDIT:

I managed to shell into my container, like so:

sudo docker exec -it docker-elk_logstash_1 bash

And found bin/logstash-plugin. The following command successfully showed plugins:

bash-4.2$ pwd
/usr/share/logstash/bin
bash-4.2$ ./logstash-plugin list

Seems the problem was that the docs are outdated. It's now named ``logstash-plugin".

sudo docker exec -it docker-elk_logstash_1 bin/logstash-plugin list

Was successful.

I debugged it by shelling into the container, like so:

sudo docker exec -it docker-elk_logstash_1 bash

Sniffed around, and found bin/logstash-plugin. The following command successfully showed plugins:

bash-4.2$ pwd
/usr/share/logstash/bin
bash-4.2$ ./logstash-plugin list
