Everything has been successfully installed!

|
${BLUE_BOLD}===== Next steps =====${RESET}
|
|
|
|
First, make sure you have everything on your path:
|
|
|
|
source ~/.bashrc
|
|
|
|
${BLUE_BOLD}Edit the Caddy config${RESET}
|
|
|
|
Get an API token from Cloudflare. The token must have the Zone / Zone / Read and
|
|
Zone / DNS / Edit permissions (as laid out in the following links).
|
|
|
|
https://github.com/caddy-dns/cloudflare
|
|
https://github.com/libdns/cloudflare
|
|
|
|
Then edit the Caddyfile:
|
|
|
|
vim /home/caddy/Caddyfile
|
|
|
|
Add the Cloudflare token to allow the ACME challenge to succeed, and add
|
|
the correct domains. (Don't forget to include both the normal and wildcard
|
|
domains.)
|
|
|
|
Also, in the CGI config, add the name of the Git branch you would like to
|
|
use when deploying. For example, a deployment of the beta site should use
|
|
the 'beta' branch.
|
|
|
|
${BLUE_BOLD}Edit the website config${RESET}
|
|
|
|
Edit the config file using a special make task:
|
|
|
|
make edit-config
|
|
|
|
Fill out everything, then rebuild the site:
|
|
|
|
make build
|
|
|
|
You don't need to deploy the site yet; wait until you've
|
|
configured everything.
|
|
|
|
${BLUE_BOLD}Edit HMN environment vars${RESET}
|
|
|
|
First, go to GitLab and add a webhook with a secret. Set it to trigger on
|
|
push events for the branch you are using for deploys.
|
|
|
|
https://git.handmade.network/hmn/hmn/hooks
|
|
|
|
Then, edit the following file and fill in all the environment vars, including
|
|
the secret value from the GitLab webhook:
|
|
|
|
/home/hmn/hmn/server/hmn.conf
|
|
|
|
${BLUE_BOLD}Configure s3cmd${RESET}
|
|
|
|
Edit the following file:
|
|
|
|
/home/hmn/.s3cfg
|
|
|
|
Add the DigitalOcean Spaces credentials, and ensure that the bucket info is correct.
|
|
|
|
${BLUE_BOLD}Configure Cinera${RESET}
|
|
|
|
Edit the following file, adding the correct domain:
|
|
|
|
/home/hmn/hmn/cinera/cinera.conf
|
|
|
|
${BLUE_BOLD}Configure the admin mailer${RESET}
|
|
|
|
Fill in the config file and build the mailer:
|
|
|
|
cd /home/hmn/hmn/adminmailer
|
|
vim config.go
|
|
go build -o /usr/bin/adminmailer .
|
|
|
|
${BLUE_BOLD}Download and restore a database backup${RESET}
|
|
|
|
make download-database
|
|
|
|
su hmn
|
|
cd ~
|
|
hmn db seedfile <your backup file>
|
|
hmn db migrate
|
|
|
|
${BLUE_BOLD}Restore static files${RESET}
|
|
|
|
make restore-static-files
|
|
|
|
${BLUE_BOLD}Set up Cinera${RESET}
|
|
|
|
cd /home/hmn/hmn/cinera
|
|
./setup.sh
|
|
|
|
${BLUE_BOLD}Start up Caddy${RESET}
|
|
|
|
systemctl start caddy
|
|
|
|
${BLUE_BOLD}Deploy the site!${RESET}
|
|
|
|
make deploy
|
|
|
|
Run 'make' on its own to see all the other tasks available to you!
