Drop-in website deployment.
Douw automates deploying new versions of websites using git and supports important features such as atomic updates, quick rollback, and DTAP environments.
NB: this is a quick guide. Run douw help for the full documentation.
First, add a site:
douw add --name example.com --remote https://github.com/Microsoft/project-html-website --env P
This creates a new, empty site under /srv/www/sites/example.com/. Now you can deploy the site:
douw deploy example.com
It is also possible to override the commit to deploy:
douw deploy example.com 7552d9968e3cf8e11698696ea3f7fd42556d62e3
And if that version contains an error you can revert to the previous version:
douw revert example.com
Or a specific version:
douw revert example.com 747bf678fac31f72441428091b755755a62dbbbd
Only a limited number of previous deployments is kept in order to save space. A cleaning job can also be triggered manually:
douw clean example.com
Or the site can be removed altogether:
douw remove example.com
By default, all sites are stored in directories with the sites' names under /srv/www/sites. In each directory, a deployments folder holds the currently available deployments. Next to the deployments is a link called current, which points to one of the local deployments. Additionally, a folder shared is linked into each deployment in order to share data between deployments in a simple way. It is therefore recommended to put public htdocs in a separate folder.
