By performing rolling upgrades of Marathon applications in DC/OS, you avoid downtime and can trade off upgrade speed, resource overhead, and application capacity. This Lab will walk you through configuring an upgrade strategy, performing a rolling upgrade, and rolling back to an earlier version of an application definition.
Upon completion of this Lab you will be able to:
- Include upgrade strategies in Marathon application definitions
- Configure upgrade strategy properties to achieve different goals
- Upgrade Marathon applications using the DC/OS GUI and CLI
You should be familiar with:
- Basic DC/OS concepts including master nodes, agents, services, tasks, and Marathon
- Working at the command-line in Linux
- AWS services knowledge is useful in order to understand the architecture of the pre-created DC/OS cluster, but not required
Before completing the Lab instructions, the environment will look as follows:
After completing the Lab instructions, the environment should look similar to:
August 1st, 2021 - Resolved an issue preventing the DC/OS cluster from provisioning
October 2nd, 2020 - Replaced CoreOS virtual machines (no longer available in AWS) with CentOS
January 10th, 2019 - Added a validation Lab Step to check the work you perform in the Lab
