We were using `server` on staging but `server1` and `server2` on
preproduction and production.
The reason behind it is we've always used one server on staging but
sometimes we've used several servers on preproduction and production.
However, this is a bit of a mess on installations which have only one
server on preproduction or production and need to use the `server` key
for the staging environments but `server1` for other environments.
So, in order to keep compatibility with existing Consul installations,
we're now allowing either `server` or `server1` on any environment.
It doesn't make much sense that by default we use one server on
production on two servers on preproduction.
Note we're keeping `server1` instead of using just `server` in order to
keep compatibility with existing installation.
The installer creates the application in the following path:
home_dir: "/home/{{{ deploy_user }}"
We update the variable "deploy_to" in the deploy-secrets
file to be consistent with the installer.
While we are modifying the file we also update the "user"
variable in staging and preproduction sections with the
installer default value: "deploy_user: deploy" the same as
we already have in the production section.
The server_name variable isn't used since we removed the Apache task in
commit 012d5297e, db_server and config_files aren't used since we
removed the capistrano templates in that same commit, and full_app_name
isn't used since commit 94a7e13dc.
The following parameters have been added to deploy-secrets.yml:
* **use_rvm**: yes/no
* **ruby_version**: Ruby version for rvm. Defaults to 2.3.2
* **repository**: Git repository. Defaults to the oficial repository
* **branch**: Branch to deploy. Defaults to master
* **rails_env**: Defaults to the stage.
Fixed migrations that required admin rights. Now first check if the postgress extensions are available. If so finish without doing nothin.
Added support for passenger.
