Installing any additional tools

If you need something you can’t find a Step for, you can always install and use tools with scripts or Script steps. Add a Script step to your Workflow, and either write your script there, or run a script from your repository. Passwordless sudo is enabled in all of our build virtual machines, so you can freely use sudo if you need it.

Once you have a working script, you can also transform it into a Step and optionally share it with others (through our StepLib). You can find a template and a README about Step creation at our Github page.

Adding a Script Step to a workflow ⚓

1. Click your app on the right side of your Dashboard.
2. Click the Workflow tab to open Workflow Editor.

3. Select a workflow in the WORKFLOW menu.

   

4. Once, you have your workflow, click the + sign to insert a Step at that position from our Step Library.
5. In the Search steps bar, search for “script” and click on the Script Step . This will add the Step to your workflow.
6. Click the Step in your workflow.
7. Insert your script into the Script content input field.

Running a script from a repo with Script Step ⚓

If you want to run a script from your repository, you can run it from this Script Step. Paths are relative to your repository’s root. For example, if you have a Bash script at path/to/script.sh you can add it to the Script content input field and run it with the following command:

bash ./path/to/script.sh

Or in a more robust form, which is better if you want to extend the content later:

#!/bin/bash
set -ex
bash ./path/to/script.sh

You can run non-Bash scripts too, for example, a Ruby script:

#!/bin/bash
set -ex
ruby ./path/to/script.rb

Examples for installing dependencies ⚓

Now you have the Script Step in your Workflow, you just have to write the script to install the dependency. You can do it in the same way as you would on your own Mac / Linux, in your Terminal / Command Line! Let’s see some examples!

brew on macOS ⚓

For example, to install cmake with a Script Step on macOS, use the following brew command:

#!/bin/bash
set -ex
brew install cmake

The whole Script content could be as short as:

brew install cmake

This is exactly how you would use brew on your Mac, but since you’ll most likely add more content to the Script Step sooner or later, the first example is a more future proof Bash script template.

apt-get on Linux ⚓

For example, to install cmake with a Script Step on Linux, use the following apt-get command:

#!/bin/bash
set -ex
sudo apt-get install -y cmake

Advanced option: use deps in bitrise.yml ⚓

Instead of installing your tool inside the Script Step, you can also use the deps option of the bitrise.yml. If you declare deps for a specific Step, the Bitrise CLI will check if that tool is installed, and will install it for you, if required.

An example, installing cmake with either apt-get (where apt-get is available), or with brew (on macOS):

deps:
  brew:
  - name: cmake
  apt_get:
  - name: cmake

A minimal bitrise.yml for demonstration:

format_version: 1.2.0
default_step_lib_source: https://github.com/bitrise-io/bitrise-steplib.git

workflows:
  test:
    steps:
    - script:
        deps:
          brew:
          - name: cmake
          apt_get:
          - name: cmake
        inputs:
          - content: |-
              #!/bin/bash
              set -ex
              which cmake

A minimal bitrise.yml for demonstration:

format_version: 1.3.0
default_step_lib_source: https://github.com/bitrise-io/bitrise-steplib.git

workflows:
  test:
    steps:
    - script:
        deps:
          brew:
          - name: awscli
            bin_name: aws
          apt_get:
          - name: awscli
            bin_name: aws
        inputs:
          - content: |-
              #!/bin/bash
              set -ex
              which aws

Conditional execution ⚓

Additionally, you can use environment variables (env vars) in your scripts too. Here is an example for the PR env var where we run different scripts for a Pull Request and for a non-Pull Request build:

#!/bin/bash
set -ex

if [[ "$PR" == "true" ]] ; then
  echo "=> Pull Request mode/build!"
  bash ./path/to/in-case-of-pull-request.sh
else
  echo "=> Not Pull Request mode/build!"
  bash ./path/to/not-pull-request.sh
fi

Note that you can use any available env var, like the ones exposed by previous steps in the Workflow.
