Portainer Deployment Overview on Server¶

Prerequisites¶

To ensure the application functions correctly, the server must meet the following requirements:

Operating System: Ubuntu, Debian, or RHEL family distributions (CentOS, Rocky Linux, AlmaLinux).
Access Rights: Superuser (root) privileges to install system packages and manage services.
Network: Internet access to Docker repositories and package managers.

The following container is installed and launched during the deployment process:

Parameter	Value
Image Name	`portainer/portainer-ce`
Container Name	`portainer`
Ports	`9000:9000`
Volumes	`/var/run/docker.sock:/var/run/docker.sock`
Restart Policy	`always`

The container uses the system Docker socket to manage other containers on the host.

The deployment process includes operating system preparation and installation of the Docker runtime environment.

Stopping automatic update services (unattended-upgrades, apt-daily).
Updating the package list and upgrading all installed system components to their latest versions.
Installing basic utilities: ca-certificates, curl, gnupg.

Adding the Docker GPG key and configuring the official Docker repository.
Installing runtime components: docker-ce, docker-ce-cli, containerd.io, docker-buildx-plugin, docker-compose-plugin and networking utilities (net-tools, bind-utils).

Installing the Docker Engine runtime environment.
Configuring the /etc/docker/daemon.json configuration file.
Activating the Docker service and configuring it to start automatically on system boot.
Installing Python management tools: python3-pip, python3-requests and libraries for interacting with Docker (python3-docker or docker).

Docker Configuration: The /etc/docker/daemon.json file is set with root ownership and 0644 permissions.
Package Security: Digital signature verification of repositories is used during the installation of system components.

Portainer container state management is performed via Docker:
