Steps:

• Make sure Docker CE is installed
• Create a directory for Wiki.js
• Create a directory for the TLS certificate files
• Create the Docker compose file
• Create the Wiki.js config file
• Create the TLS certificate files
• Start up Wiki.js and run through the installation and configuration process

mkdir ~/wikijs

mkdir ~/wikijs/certs

docker-compose.yml

docker-compose up -d

Afterwards:

• Open the HTTP version of the wiki
• Create an account and set the URL to the HTTP domain
• Open the HTTPS version of the wiki
• Go to Administration > SSL > Redirect HTTP requests to HTTPS and choose Turn on
