# Install Portainer CE with Docker on Linux ##### Link: [https://docs.portainer.io/start/install-ce/server/docker/linux](https://docs.portainer.io/start/install-ce/server/docker/linux) ##### **Introduction** ##### Portainer consists of two elements, the Portainer Server, and the Portainer Agent. Both elements run as lightweight Docker containers on a Docker engine. This document will help you install the Portainer Server container on your Linux environment. To add a new Linux environment to an existing Portainer Server installation, please refer to the Portainer Agent installation instructions. ##### To get started, you will need: - ##### The latest version of Docker installed and working. We recommend following the official installation instructions for Docker - in particular, we advise against installing Docker via snap on Ubuntu distributions as you may run into compatibility issues. - sudo access on the machine that will host your Portainer Server instance; - By default, Portainer Server will expose the UI over port 9443 and expose a TCP tunnel server over port 8000. The latter is optional and is only required if you plan to use the Edge compute features with Edge agents. ##### The installation instructions also make the following assumptions about your environment: - ##### Your environment meets our requirements. While Portainer may work with other configurations, it may require configuration changes or have limited functionality. - You are accessing Docker via Unix sockets. Alternatively, you can also connect via TCP. - SELinux is disabled on the machine running Docker. If you require SELinux, you will need to pass the --privileged flag to Docker when deploying Portainer. - Docker is running as root. Portainer with rootless Docker has some limitations, and requires additional configuration. ##### **Deployment** ##### First, create the volume that Portainer Server will use to store its database: ##### *docker volume create portainer\_data* ##### Then, download and install the Portainer Server container: ##### *docker run -d -p 8000:8000 -p 9443:9443 --name portainer --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer\_data:/data portainer/portainer-ce:2.21.0* ##### By default, Portainer generates and uses a self-signed SSL certificate to secure port 9443. Alternatively you can provide your own SSL certificate during installation or via the Portainer UI after installation is complete. ##### If you require HTTP port 9000 open for legacy reasons, add the following to your docker run command: ##### -p 9000:9000 ##### Portainer Server has now been installed. You can check to see whether the Portainer Server container has started by running docker ps: ##### root@server:~# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES de5b28eb2fa9 portainer/portainer-ce:2.21.0 "/portainer" 2 weeks ago Up 9 days 0.0.0.0:8000->8000/tcp, :::8000->8000/tcp, 0.0.0.0:9443->9443/tcp, :::9443->9443/tcp portainer ##### **Logging In** ##### Now that the installation is complete, you can log into your Portainer Server instance by opening a web browser and going to: ##### *[https://localhost:9443](https://localhost:9443)* ##### Replace localhost with the relevant IP address or FQDN if needed, and adjust the port if you changed it earlier. ##### You will be presented with the initial setup page for Portainer Server.
