Problems running a new node

Hi! I’m new in Algorand word. I’m trying to run a node via Algorand Studio but i got some errors. Can anyone helps me? Please.
This is the errors:

docker run -dt --rm --name algorand-MyNode-2.4.1 -p 8080:8080 -v algorand-MyNode:/data algorand/stable:2.4.1 /bin/bash
docker: Error response from daemon: driver failed programming external connectivity on endpoint algorand-MyNode-2.4.1 (c10b87d025b3f66bd2fbb06bf4d815332ebe4fb72def150d6dfc982f86fbf87b): Error starting userland proxy: listen tcp4 bind: address already in use.
docker exec algorand-MyNode-2.4.1 ./goal node start -d /data -l
Error: No such container: algorand-MyNode-2.4.1
docker exec algorand-MyNode-2.4.1 cat /data/algod.token
Error: No such container: algorand-MyNode-2.4.1

docker exec algorand-MyNode-2.4.1 ./carpenter -color -d /data
Error: No such container: algorand-MyNode-2.4.1

It looks like a Docker error.

Is Docker started?
Which OS are you on?
Can you try to run docker run hello-world in a terminal?

It also looks like you failed to start the container because something had already claimed port 8080, you can review the containers running with docker container ls

Docker are started.
I’m on Ubuntu 20.04.
The command ‘docker run hello-world’ run.

If i type ‘docker container ls’ return black output. No container uses 8080 Port. :confused:

Blank* output, Sorry for my english

Can you check that no other application is using port 8080?

algorand service listening on port 8080:
tcp 0 0* LISTEN 687/algod

It’s a problem?

thanks to fabrice i found that the ‘algod’ process was listening on port 8080.
I killed it with the command 'sudo kill -9 '.
So I managed to start the node!
How can I join the network to get rewards?

The participation rewards are described in

You do not need to actually have a participation node to earn them.
However, we encourage people to have one to help the network.
