The starting point is... guess what...: getting started from the official doc.
You shall therefore prepare
- a fresh installation of ubuntu. I used 18.04 (eventhough 16.04 is recommended) and the installation script ran smoothly
- a DNS entry to the IP of this brand new server, e.g: dokku.me
Just browse by https://dokku.me, where you are be kindly asked for your public SSH key which you could quickly pick up from a cat ~/.ssh/id_rsa.pub | pbcopy
Note that once this setup complete, https://dokku.me is not available anymore
On the server side, I like to have access to docker commands without sudo, hence a quick sudo adduser myself docker to add myself in the docker group. Logout and login again, and docker ps (for instance) will output the expected :
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
As will next section will prove, this is unncessary since all commands are done with dokku (instead of docker) which prompts your password anyways.
Just before jumping onto Ghost make sure to follow the getting started guide down to the end. It helped me in any case...
I had created and deployed ruby-rails-sample, but the subdomain configuration did not really work out of the box for me(ruby-rails-sample.dokku.me does not return anything)... It required to have configured a DNS entry on *.dokku.me.
That allows the next steps to work out smoothly, and to spawn ghosts in any subdomain you like, just like mosquitos
On the host side, create an app and apply a few settings:
# register app in dokku
dokku apps:create ghost
# declare the 'url' environment variable needed by ghost
dokku config:set ghost url=https://ghost.dokku.me
# prepare the redirection to the container's port
dokku proxy:ports-add ghost http:80:2368
On my side, I create repo with only one file, the Dockerfile
FROM ghost:2-alpine
And I push the app
git remote add ghost [email protected]:ghost
git push ghost master
Would I wish a second blog now, I would repeat those steps:
# on host
dokku apps:create another
dokku config:set another url=https://another.dokku.me
dokku proxy:ports-add ghost http:80:2638
# on my side
git remote add another [email protected]:another
git push another master
Well, let's be old-fashioned and have a cosy Makefile there... you will be able to create and destroy apps with a single command. That's always handy.
