add a docker container to netdata docker as new node

Question

Netdata has been installed on docker container. I tied to add new docker container into netdata.cloud as below; I tried to run below command in host docker server

docker exec -it php7.4-apache2 netdata-claim.sh -token=token -rooms=my_room2 -url=https://app.netdata.cloud
docker exec -it php7.4-apache2 /usr/sbin/netdata-claim.sh -token=token -rooms=my_room2 -url=https://app.netdata.cloud

I tried to run below command in php7.4-apache2 container

sudo netdata-claim.sh -token= -rooms=my_room2 -url=https://app.netdata.cloud

But end up with

OCI runtime exec failed: exec failed: container_linux.go:370: starting container process caused: exec: "netdata-claim.sh": executable file not found in $PATH: unknown

I would like some suggestions from expertise.

Answer 1

Try providing relative paths (and not only filenames) when executing sh-files by adding ./, for example:

sudo ./netdata-claim.sh <...>

Answer 2

First of all you can most certainly monitor other containers while having netdata installed as a docker container.

To claim the netdata container, you should be able to do it via running this command on the host machine:

docker exec -it netdata netdata-claim.sh -token=98FMbk9sx-22f75VU2FiC2xzoeeN8umkxDmh8zeeOKACCkevYBSCOU2B0o7g75-cUXc0QpLZ6ej-ZvSokSWelisrncFwi4RXFfpkNexBXv8UnHSDkvccjv0xjBYFPww-Vu28coQ -rooms=abb4d556-6d1f-46a1-a04d-663b86ccf4ea -url=https://app.netdata.cloud

Please note that the netdata just after -it is the name of the container that runs netdata, so in case the name of the container is a different one, you will have to change that part of the command(e.g docker exec -it <container_name> ..)

Keep us posted if you make it work!
