What is Portainer?

Portainer is a lightweight, open-source platform that simplifies the management of containerized applications running on Docker, Kubernetes, and other environments for container orchestration. The main objective of Portainer is to provide a graphical interface to manage Docker containers and Docker groups, making it easy to use and freeing the system administrator or developer from the complexity of managing the containers through the command line. Developers and system administrators can accomplish all this through a web-based dashboard that monitors, deploys, and manages containers, networks, images, and volumes in Portainer.

Portainer supports single-node and multi-node environments, such as Docker Swarm, Kubernetes clusters, and Nomad environments. Its functionalities include managing the lifecycle of containers (start/stop/delete), monitoring resources, log access, and role-based access control to handle multi-user environments easily and securely. It also provides native integration for both Docker Compose and Kubernetes manifests to enable deployments of multi-container applications easily.

It is of real value to administrators who need greater visibility and control over their infrastructure, especially in a production environment. It is easy to adopt among new users and is popular for small teams and large enterprises that require an efficient, streamlined method of container management and orchestration of complex applications.

Features of Portainer

Portainer provides features that make it easier to operate containerized applications. Some significant features are as follows:

1. User-friendly Web Interface

Portainer UI offers an easy-to-use, web-based GUI that ensures that everything related to managing a container, network, volume, and images is implemented with less reliance on the command line.

2. Multi-platform Support

It supports multiple platforms:

  • Docker: Portainer manages either a single-host or Docker Swarm environment.
  • Kubernetes: It manages Kubernetes clusters and workloads.
  • Nomad: Portainer offers integration capabilities for the orchestrator, HashiCorp Nomad.

3. Container Life Cycle Management

Allows for various operations, such as starting, stopping, restarting, pausing, and deleting a container.

4. Image Management

Pulls images from registries and manages local image repositories. Also deletes unused images and integrates with private Docker registries.

5. Stack Management

Allows deployment and management of multi-container applications using Docker Compose or Kubernetes manifests, also known as Helm charts for Kubernetes.

6. Volume and Network Management

Simplifies the creation, management, and deletion of Docker containers, volumes, and networks. You are entirely in control over your persistent data and network configurations.

7. Role-based Access Control (RBAC)

Controls access and permissions for different users in the environment, providing fine-grained control over who can do what.

8. Logs and Monitoring

Provides real-time container logs and performance metrics, like CPU and memory usage, to help monitor and debug.

9. Templates and App Catalog

Offers ready-made application templates that simplify the deployment of common services or apps.

10. External Authentication

Supports two types of authentication systems, LDAP and OAuth-based, which strengthen security and provide solid integration with corporate environments.

11. Backup and Restore

Allows the capability to back up and restore Portainer's settings and environments to ensure a recovery process in case of failures.

12. API Access

Allows programmatic control and integration of external tools through a full-featured API.

These features make Portainer great for containerized application administrators working in development, testing, or production environments, suitable for both novices and veterans alike.

Install Portainer

Portainer consists of two main components: the Portainer Server and the Portainer Agent. These are extremely lightweight Docker containers that run on a Docker engine. Here, we will guide you through the steps to install a Portainer Server container within your Windows environment with WSL and Docker Desktop already installed.

Requirements

  • Have Docker and the latest version of Docker Desktop installed.
  • Administrative access to the machine to host your instance of Portainer Server.
  • WSL2 and a Linux distribution installed and activated. Ensure that WSL2 is installed before installing a Linux distribution.
  • By default, the Portainer Server exposes the UI over port 9443 and a TCP tunnel server over port 8000. The latter is necessary only if you are using the Edge compute features with Edge agents.

Steps to Install Portainer

To store the database on the Portainer Server, first, create the volume:

docker volume create portainer_data
docker volume create portainer_data
SHELL

Then, use PowerShell or the Command Prompt with Docker CLI to execute the following command to download and install, and then create 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:latest
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:latest
SHELL

You now have the Portainer Server installed. You can determine if the Portainer Server container is running with this command:

docker ps
docker ps
SHELL

Logging into Portainer

Once installation is complete, access your Portainer Server instance in a web browser at https://localhost:9443. Replace localhost with the appropriate IP address or FQDN if necessary and adjust the port if it was changed. You will be presented with the initial setup page of the Portainer Server.

The first user will be the administrator. Although 'admin' is the default login, you can modify it. The password should meet the specified parameters and have a minimum length of 12 characters. On the next page, enter the Portainer Community Edition license key you received, paste it into the appropriate box, and then press Submit.

Next, the system will redirect you to the Portainer dashboard, where you can view the list of environments available on the machine. You can connect to existing Docker containers by clicking the connect button.

Click "Add Environments" to manage additional environments with this Portainer instance. Otherwise, select "Get Started" to begin utilizing Portainer.

curl -X 'POST' \
  'http://localhost:8080/v1/document-services/pdfs/encrypt?user_password=demo' \
  -H 'accept: */*' \
  -H 'Content-Type: multipart/form-data' \
  -F 'pdf_file=@test.pdf;type=application/pdf'
curl -X 'POST' \
  'http://localhost:8080/v1/document-services/pdfs/encrypt?user_password=demo' \
  -H 'accept: */*' \
  -H 'Content-Type: multipart/form-data' \
  -F 'pdf_file=@test.pdf;type=application/pdf'
SHELL

This command sends the document to IronSecureDoc, which applies the specified encryption.
