Hello everyone,  
How do I move forward with setting up and contributions, I have selected PBM sdk and PBM backup throttling for GSOC 25 I will be going for 1 of them after setting up the PMM server dashboard on localhost/IP address How do I move forward?  
I am still yet to setup PMM client I have set up and running PBM agent and PMM server and in the process of PMM client for MongoDB. Any help is appreciated.

```

I’m exploring PBM and PMM and have already set up the dashboard. I want to ensure I’ve completed the necessary setup so I can focus on understanding the codebase and contributing. Right now, I’m deep in the docs, but I’d appreciate guidance on what I might be missing and which components are essential. If someone with experience could help me finalize the setup, I can shift my focus to learning and contributing effectively.  
And I am not able to clone pmm repo

```auto

Try git clone over ssh, it’s more convenient than https

```auto
git clone git@github.com:yashpal2104/pmm.git

```

You will most likely need to add your computer’s SSH key to your GitHub profile settings, there are instructions there.

How have you installed MongoDB? What CPU/Memory and OS do you use?  
I recommend to start on Docker - as it’s the easiest setup.

This is the error log with docker

I have done `docker container rm /psmdb` still same problem and when I do `docker container ls` I can’t see “psmdb” name container

Not trying to be annoying but I am still not able to understand what the problem is and what am I trying to install like the components are too advanced I am reading the docs but I am not able to navigate and get to a conclusion. Can I get an idea about what are the necessary components or the minimum things like server, dashboard, etc that I need as starting out so that I can start analysing the codebase of PBM projects and start analysing and reading code to understand what needs improvement?

Have you followed this procedure? [Run in Docker - Percona Server for MongoDB 8.0](https://docs.percona.com/percona-server-for-mongodb/8.0/install/docker.html)

Yes but trouble connecting with `mongosh` shell

```auto
root@yodaone:~# docker run -it --link psmdb --rm percona/percona-server-mongodb:8.0 mongosh mongodb://172.17.0.2:27017/DB_NAME
docker: Error response from daemon: Cannot link to a non running container: /psmdb AS /sad_goldberg/psmdb.

docker: Error response from daemon: Cannot link to a non running container: /psmdb AS /intelligent_swanson/psmdb.

```

and using this command  
`docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' psmdb`  
there is blank/no output

I guess because the container does not start. Have you checked container logs?

That log looks proper. Any errors you can see in the log?

Some sort of authentication error, is this might be associated with docker desktop sign-in?

```

It is more than this(errors) but I copied the last ones.

I dont know if this information is required but maybe firewall might be active although I checked it is not right now but sometimes it is because I am using my college’s LAN network, but this problem was before when I was on windows after I switched to Linux there has not been any problem running Docker(previously it was problematic to run docker desktop on windows)

No I don’t think they are relevant. But from your previous message I can see you have 3 instances already running:

have you tried to run `mongosh` inside the container?

Yes this time I ran inside container bash shell

Can you try `mongosh` on a container that is running on port `27017` ? Or use `mongosh` with a different connection string to use appropriate port. See: [https://www.mongodb.com/docs/manual/reference/connection-string-options/](https://www.mongodb.com/docs/manual/reference/connection-string-options/)

All in all - you get `ECONNREFUSED` because on that address there’s no `mongod` that is running.

@radoslaw.szulgo  
I got to know the problem but not the solution I have the pesmdb container but it is showing 0bytes in it and it is not binded to a port because rs101 is taking its place since both have same port.  
Attached screenshot below and this is the tag I downloaded is this correct? `percona/percona-server-mongodb:8.0.4-1-multi`  
Let me know if more information to provide  
Also what do I put instead of **DB\_NAME** I have not created a database `docker run -it --link psmdb --rm percona/percona-server-mongodb:8.0 mongosh mongodb://MONGODB_SERVER:PORT/DB_NAME`
