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. ```auto [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'.

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. ---

Thank you so much Michael. Just to get clarity, can I run the below commands in the existing docker instance ? ---

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. ---

Thanks Mike. I often get this error in my PMM server. ![image](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/2X/d/d62f3e89d89f03adc499ef292a0ae08d5f510d60.png) How do i resolve this ? ---

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`). ---
