GitLab CI vs Bamboo

All build setup are stored in .gitlab-ci.yml file, which is versioned and stored in the project. Like Travis do.

All of GitLab CI's code is open source and under the MIT license.

Tests are parallelized across multiple machines in order to reduce test times considerably.

Good integration with Docker.

The tests of GitLab CI run parallel to each other and are distributed on different machines. Developers can add as many machines as they want or need, making GitLab CI highly scalable to the development team's needs.

Since it uses the GitLab API for setting up hooks, the setup of GitLab CI for projects hosted on GitLab can be done in one click.

Easy to test and deploy on Kubernetes.

Bamboo is the only build server to offer first-class support for the "delivery" aspect of continuous delivery. Deployment projects automate the tedium right out of releasing into each environment, while letting you control the flow with per-environment permissions.

When connecting Bamboo with Stash and JIRA, details like JIRA issues, commits, reviews and approvals follow each release from development to production. If HipCHat is part of the integration, team members get notified right away in addition to email notifications.

Bamboo allows using Docker containers to create build agents. Using Docker agents lets you run multiple remote agents on the same host without conflicting requirements. It makes it easier to duplicate and distribute changes to build agents, and to use scripts for creating and maintaining agents.

How can you define and build your own image and push it to a registry to share? This is when Bamboo’s Docker tasks come into play. Docker tasks make it possible to build an image, run a container, and push a Docker image to a registry from within your build or deployment project.

Bamboo allows you to automatically detect and build new branches, merge branches together when tests pass and continuously deploy code to staging and production servers based on branch name.

Out-of-the-box features that let developers perform parallel testing on elastic agents and quarantine flakey tests.

Avoid plugin hell by having most important capabilities as out-of-the-box features, not plugins. Bamboo is not just built for teams, but teams-of-teams. It has the administrative features you need to manage and maintain CI at scale. Enterprise model for access control, management, and support.

Deploying applications with AWS CodeDeploy was always possible by using Bamboo script tasks, and it's now an easier process with a bundled add-on and its accompanying CodeDeploy task.

Bamboo can also be integrated with Amazon S3 for unlimited storage.
