Docker port issue

[velumal]

I am in the process setting up PMM using the docker in a linux machine.
while trying to launch the PMM server i am getting the below port connectivity error.

[aquaman@lxrepfmsdev01 ~]$ docker run -d -p 80:80 -p 449:443 --volumes-from pmm-data --name pmm-server --restart always percona/pmm-server:2
docker: Error response from daemon: Conflict. The container name "/pmm-server" is already in use by container "3da7c52b1f23f697454016a9b7f5fdecde20a29dfb7549c7ff64df41036c332c". You have to remove (or rename) that container to be able to reuse that name.
See 'docker run --help'.

I have tried using multiple ports and tried updating the ipv6 settings like mentioned in the below link .

Enable IPv6 support

But none of them seems to work.

Can somebody help me on addressing this error ?

Hi @velumal thank you for posting!
I tried to reproduce your scenario but I cannot. I provisioned an Ubuntu 20.04 instance and installed Docker stable. I was able to bring up PMM Server cleanly:

root@ubuntu-s-1vcpu-1gb-nyc3-01:~# docker ps -a
CONTAINER ID   IMAGE                  COMMAND                CREATED         STATUS                   PORTS                                           NAMES
9c07cbdc88a2   percona/pmm-server:2   "/opt/entrypoint.sh"   5 minutes ago   Up 5 minutes (healthy)   80/tcp, 0.0.0.0:443->443/tcp, :::443->443/tcp   pmm-server
33be1b4e5be2   percona/pmm-server:2   "/bin/true"            5 minutes ago   Created                                                                  pmm-data

Here are the commands I executed:

apt-get remove docker docker-engine docker.io containerd runc
apt-get install     apt-transport-https     ca-certificates     curl     gnupg     lsb-release
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
echo   "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
apt-get install docker-ce docker-ce-cli containerd.io
systemctl start docker
docker create --volume /srv --name pmm-data percona/pmm-server:2 /bin/true
docker run --detach --restart always --publish 443:443 --volumes-from pmm-data --name pmm-server percona/pmm-server:2

PMM Server does not require IPv6 so if this appears to be a source of contention you can safely disable it in docker and at the OS level.

[velumal]

Thank you so much Michael.

Just to get clarity, can I run the below commands in the existing docker instance ?

[Michael_Coburn]

Hi @velumal
The commands I posted are intended to be executed from the linux host outside of the container, they are what I used to deploy a new PMM Server from scratch.

[velumal]

Thanks Mike.
I often get this error in my PMM server.

How do i resolve this ?

[Michael_Coburn]

Hi @velumal
This error is due to grafana not being able to start properly. The cause I usually see is due to disk-full conditions, check whether you have exhausted all space on the mountpoint where you store your docker volumes (usually under /var/lib/docker).
