If your master.key has been compromised, you might want to regenerate it.

No key regeneration feature at the moment. We have to do it manually.

1. Copy content of original credentials rails credentials:show somewhere temporarily.
2. Remove config/master.key and config/credentials.yml.enc
3. Run EDITOR=vim rails credentials:edit in the terminal: This command will create a new master.key and credentials.yml.enc if they do not exist.
4. Paste the original credentials you copied (step 1) in the new credentials file (and save + quit vim)
5. Add and Commit the file config/credentials.yml.enc

Ubuntu 16 default python is almost python 3

Loads of solutions exist, but for changing the system default, alias is not the way to go.

$ update-alternatives --list python update-alternatives: error: no alternatives for python

Services declared as oneshot are expected to take some action and exit immediatelly (thus, they are not really services, no running processes remain). A common pattern for these type of service is to be defined by a setup and a teardown action.

Let's create a example foo service that when started creates a file, and when stopped it deletes it.

Define setup/teardown actions

Create executable file /opt/foo/setup-foo.sh:

# PostgreSQL can be on a remote server but you'll need root privileges in Linux and superuser in PostgreSQL.

# First install build tools

sudo su
aptitude install build-essential
aptitude install postgresql-server-dev-9.4

# Clone and build the PL/pgSQL server-side debugger
