Migrating from Bamboo
Migrating continuous integration tools can be hard, so we've put together a guide to help you transition your Bamboo skills to Buildkite. This guide is applicable to both Bamboo Sever and Bamboo Cloud.

Plans to Pipelines
Most Bamboo workflows can be easily mapped to Buildkite. Projects and Plans in Bamboo are known simply as Pipelines in Buildkite. Bamboo Deployments also simply become Buildkite Pipelines.
Buildkite Pipelines consist of Steps. There are 4 different types of Pipeline Steps:
The first two types,
trigger, run in parallel. The second two types,
block will cause the Pipeline to pause and wait for all previous steps to complete—this way your Pipeline becomes a set of stages.
For example, a simple test and deploy Pipeline might consist of the following steps:
steps: # First stage - command: test_1.sh - command: test_2.sh - wait # Second stage - command: deploy.sh
block step will also wait for previous steps to complete but instead of automatically continuing, it will stop the build and require a user to manually "Unblock" the Pipeline by clicking the "Continue" button in the web interface, or use the Unblock Job REST API endpoint. These are the equivalent of a Manual Stage in Bamboo.
steps: - command: test_1.sh - command: test_2.sh - block: 'Deploy to Production' - command: deploy.sh
Let’s look at an example Bamboo Plan:
We can map this to a Buildkite Pipeline using a combination of
Creating and managing your Pipelines can be done in a variety of ways, the easiest being the Buildkite web interface. If you have many Pipelines to migrate or manage at once, you can use the Update Pipeline REST API.
Once you’ve become familiar with the tooling and concepts you can switch to
storing your Pipelines as code. The above Bamboo
Plan that we mapped to Buildkite could also be defined using the following
steps: # First stage is to run the "make" command - which will compile our # application and store the binaries in a `build` folder. We'll upload the # contents of that folder as an Artifact to Buildkite. - command: "make" artifact_paths: "build/*" # To prevent the "make test" stage from running before "make" has finished, # we seperate the command with a "wait" step. - wait # Before running `make test` we need to download the artifacts created in the # previous step. To do this, we can we the `buildkite-agent artifact # download` command. - command: | mkdir build buildkite-agent artifact download "build/*" "build/" make test # By putting commands next to each other, we can make them run in parallel. - command: | mkdir build buildkite-agent artifact download "build/*" "build/" make lint - block: "Deploy to production" - command: "scripts/deploy.sh"
Once your Build Pipelines are setup, you can update step labels to something a bit more fun than just text 😃 (see our extensive list of supported emojis)
Steps and Tasks
command steps are Buildkite's version of the Command Task in Bamboo - they
can run any commands you like on your build server, whether it's
rake test or
make. Buildkite doesn't have the concept of Tasks in general, it's up to
you to write scripts that perform the same tasks that your Bamboo Jobs have.
For example, say you had the following set of Bamboo Tasks:
This can be rewritten to be a single script and then committed to your repository. The Buildkite Agent takes care of checking out the repository for you before each step, so the script would simply be:
#!/bin/bash # These commands are run within the context of your repository echo "--- Running specs" rake specs echo "--- Running cucumber tests" rake cucumber
Read our Writing Build Scripts guide if you'd like to learn more about how to write build scripts and some common best practices.
trigger steps can be used to trigger builds in other Pipelines. You can use
these to create dependent Pipelines. See our
example for more information.
Remote and Elastic Agents
The Buildkite Agent replaces your Bamboo Remote Agents. You can install the Buildkite Agent onto any server to run your builds.
In Bamboo, you can target specific agents for your jobs via their Capabilities, in Buildkite you target them using meta-data.
Similar to Elastic Bamboo, Buildkite can also manage a fleet of Agents for you on AWS using our Buildkite AWS Stack. Buildkite doesn’t limit the number agents you can run at any one time, so by using the Buildkite AWS Stack you can auto-scale your build infrastructure, going from 0 to 1000’s of agents within moments.
Authentication and Permissions
Buildkite supports single sign-on with Okta, OneLogin, Bitium, Active Directory (ADFS), Google Apps and SAML.
For larger teams, it can be useful to control what users have access to which Pipelines. We're currently rolling out Buildkite Teams as a new feature to the platform. Contact us if you'd like to be part of the beta.
