Portainer.
On your own server.

Manage container environments through a browser-based administration interface.

What it is for.

Common uses of Portainer.

Common uses

  • Container administration
  • Stack organisation
  • Environment visibility

Keep in mind

Container-management permissions are powerful. Restrict the dashboard and understand the privileges granted by Docker access.

Installed for you?
No. Your preference is saved with your configuration

Before you install

Check the current supported operating systems, deployment methods, dependencies and licence terms. What you need depends on your workload, not just the application's name.

Large datasets and busy workloads can need far more memory, storage or different hardware. Any external API or service subscriptions are separate.

Things to decide before you install Portainer.

Advice specific to this application.

Management access reaches the workload

Container administration can affect running services, network connections and persistent data. Decide which environments and users need management access. Protect the administration interface and review permissions before attaching another container host.

Back up workloads independently

A management dashboard does not make every container persistent. Identify volumes, application databases and the definitions needed to recreate the services. Keep a recovery process that still works if the dashboard or the original host is unavailable.

Get the server ready.

Linux guides that help with this setup.

A repeatable deployment.

Four steps that make the environment easier to maintain.

  1. 01

    Check requirements

    Read the publisher's instructions and choose a supported installation method.

  2. 02

    Limit access

    Protect the dashboard, credentials and network endpoints before you expose any service.

  3. 03

    Persist your data

    Work out where the application keeps its state and store it separately from replaceable runtime files.

  4. 04

    Test recovery

    Back up the data and configuration, then check that you can restore them.

A checklist to keep.

Run through it before and after you install.

Portainer questions.

Quick answers before you choose resources.

Does choosing this application install it?

No. The configurator only saves your application preference. It does not connect to any infrastructure or run an installer.

How much memory will I need?

Use the planning example as a starting point only. Check the publisher's requirements and measure the whole stack under a realistic workload.

Who maintains the application?

You do. Self-hosted applications need updates, configuration and recovery planning from the operator. The publisher's documentation describes supported maintenance.

Where can I learn the server basics?

The knowledge base covers Linux access, packages, services, firewalls and backups.
