If you need to clone a private GitHub repository without an SSH key you can use a Personal Access Token. This can be useful in a build/deployment pipeline for example where you are using a programmatic GitHub user to clone into a temporary server or container. You can then pass the token and other information via environment variables.
Iterate over set for resource using count and index in Terraform
Even in Terraform 0.12 you cannot use iteration with resources, so you may still have to resort to using count to create multiple resources.
However you cannot iterate over a set (unlike a list) normally because it has no indices. Luckily Terraform will convert sets to lists without modifying the order of items, which allows you to use count and index as you would with a list.

Allow connection to PostgreSQL server outside localhost
If PostgreSQL is set to only listen and allow connections from localhost (127.0.0.1) then you can change the configuration to allow other or all IP addresses to connect.

Previously I’ve saved these to the filesystem as per a handy UCSF guide and updated myself for Behat 3. However if you do not have easy access to the filesystem where Behat is being run, such as your Continuous Integration...
