Detailed explanation of docker visualization graphics tool portainer

1. Introduction to Portainer

Portainer is a graphical management tool for visualizing container images. Portainer can be used to easily build, manage, and maintain the Docker environment. It is completely free and based on containerized installation method, which makes deployment convenient and efficient.

2. Portainer Architecture Overview

Portainer consists of two elements: Portainer Server and Portainer Agent. Both run as lightweight containers on your existing containerized infrastructure. Portainer Agent should be deployed to each node in the cluster and configured to report to the Portainer Server container.
A single Portainer Server will accept connections from any number of Portainer Agents, providing the ability to manage multiple clusters from a centralized interface. To do this, the Portainer Server container requires data persistence. Portainer Agent is stateless and data is shipped back to the Portainer Server container.

3. Requirements for installing Portainer

1. Persistent Storage
Portainer Server requires persistent storage to maintain the database and configuration information required for its operation. The installation process provides a basic storage configuration for our platform. By default, both Docker and Kubernetes provide only local storage, and if cluster-wide persistent storage is required, it is recommended to implement it at the infrastructure level.
2. Install the latest version of Docker
Installation address

Fourth, install Portainer using Docker on Linux

1. First, create the volume that Portainer Server will use to store its database:

docker volume create portainer_data

2. Download and install the Portainer Server container:

docker run -d -p 8000:8000 -p 9000:9000 --name=portainer --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer

3. The Portainer server is now installed. You can check if the Portainer Server container is started by running the following command:

docker ps -a

4. By opening a web browser and going to:

http://localhost:9000/

5. Install Portainer Agent using docker on Linux

Run the following command to deploy the Portainer Agent:

docker run -d -p 9001:9001 --name portainer_agent --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v /var/lib/docker/volumes:/var/lib/docker/volumes portainer/agent:latest
