Arangodb Docker Container: Could not connect to endpoint 'tcp://127.0.0.1:8529', database: '_system', username: 'root' docker

Question

I've installed ArangoDb in Ubuntu 20.04 through docker , and started an instance:

raphy@pc:~$ sudo docker run -e ARANGO_RANDOM_ROOT_PASSWORD=1 -d --name arangodb-instance arangodb/arangodb
ca6c80f7895c1e6b379937c8b2e71a3d0134ab0d39b09b87ecd2a0feb55b53e4
raphy@pc:~$ sudo docker run -e ARANGO_RANDOM_ROOT_PASSWORD=1 --name playground --link arangodb-instance:db-link arangodb/arangodb

Now, I want to use ArangoShell :

I opened another console

raphy@pc:~$ sudo docker ps

CONTAINER ID   IMAGE               COMMAND                  CREATED          STATUS          PORTS      NAMES

ca6c80f7895c   arangodb/arangodb   "/entrypoint.sh aran…"   34 minutes ago   Up 34 minutes   8529/tcp   arangodb-instance

But , trying to follow these indications: https://hub.docker.com/r/arangodb/arangodb/

I get this error:

Could not connect to endpoint 'tcp://127.0.0.1:8529', database: '_system', username: 'root'

raphy@pc:~$ sudo docker exec playground arangosh
