The simplest and fastest way to install Outline Wiki is to use the Portainer template prepared by our team. This method minimizes manual configuration and allows you to deploy a stable, ready-to-use knowledge base in just a few minutes.
Requirements:
-
VPS with Portainer installed using the Unihost script
-
Installed Redis server
-
Installed PostgreSQL server
-
Deployed NPM (Nginx Proxy Manager)
-
Credentials for the mail server
After connecting to Portainer, go to the Application section, select Outline Wiki, and fill in the required fields.
Fill in all the required fields. Please note: for security, the password must be strong — use uppercase and lowercase letters, numbers, and special characters to minimize the risk of unauthorized access.
Also note: if you want to deploy the wiki locally and use a domain specified in the hosts file, make sure to set it in the OUTLINE_URL= field.
After that, a new Wiki stack will appear in the Stacks section. Inside this stack, the containers required for its operation will be deployed.
To access Outline Wiki, you need to configure proxying through Nginx Proxy Manager (NPM).
-
Use your own domain and create an A record pointing to your server’s IP address.
-
In NPM, create a new Proxy Host and fill in the fields as shown in the screenshot below.
If you don’t have a domain, you can use a test one (for example, wiki.local) by adding it to your machine’s hosts file.
Then, in NPM, create a new Proxy Host and complete the fields according to the example in the screenshot:
After navigating to your domain, the workspace creation page will open. Enter the required details and complete the setup.
Once you create the workspace, you will gain access to the admin panel.
Conclusion
Using the ready-made Outline Wiki template in Portainer allows you to deploy a wiki system without complex manual configuration. Combined with NPM, you get convenient access to the panel, while Outline’s built-in features provide efficient documentation management and seamless team collaboration. As a result, you have an out-of-the-box solution that saves time and simplifies knowledge base management.
