Environment variables

Environment variables are pairs of key-and-value that can be used in the pipelines instead of manually updating the same values. They allow developers to save time looking up and entering access details, and eliminate the risk of providing sensitive details in their scripts.

ENV VARs are used to parameterize build scripts. Setting up variables in a pipeline will cause the same build action to work differently depending on the pipeline.

Setting Environment Variables

When adding a new variable, the following fields are available:

• Scope
  • defines the level of the variable
• Encryption
  • enabling encryption will hide the value of the variable in the logs
• Type
  • if you set it to Fixed, the value of the variable will always be the same. Switching the option to Settable will let you change the value and pass it to the next action or execution

Environment Variables can be defined on 4 levels:

1. Workspace
   • available for all projects and pipelines. Configured in the workspace Preferences.
2. Project
   • available for all pipelines in the project. Configured in the Project Options.
3. Pipeline
   • available only for the pipeline where was created (eg. production server details). Configured in the pipeline details.
4. Action
   • available only for the actions where the variable was defined

Workspace environment variables

Example Usage

Let's configure some variables to encrypt access to an FTP server:

1. Go to your deployment pipeline and click the Variables tab
2. Add variables with the corresponding values. For example:
   • Hostname: FTP_HOST / 192.168.0.100
   • Login: FTP_LOGIN / admin
   • Password: FTP_PASS / buddy1234

Configuring environment variables

3. Now you can use the variables to store access credentials to your deployment server:

Using variables in action

Fields that support ENV VARs

Environment variables are supported across the whole service, but most commonly used in the build actions. You can predict a variable by entering $ at the beginning of the supported field:

Run commands box

Here's the list of the currently supported fields:

You cannot type there anything on the front-end. Add this action using REST API or YAML - used variables should work there with no problems.

Default Environment Variables

Buddy populates a number of environment variables during each execution - for example the branch from which you deploy and the ID of the execution. Here is the list of populated variables:

Below you can find a list of exemplary values for the abovementioned variables:

Passing variables between actions

Passing variables within one pipeline is useful, e.g. when we want to assign file content to a variable and send it in a notification:

Variable passing pipeline example

Passing variables between executions

You can pass the values of variables between executions as well. The values can be saved in one execution and then used in another one, e.g. you can set a variable with the version type and increment it in every execution.

Passing variables between pipelines

You can pass a variable between pipelines using the Run next pipeline action:

1. Go into the Variables tab in the action details.
2. Define the name of the variable and the value to pass: Variables tab

Passing variables on execution start

You can parameterize your execution using the Pass arguments action - it will pause the pipeline and wait for your input to proceed:
