Automation

Deployment Rollbacks via FireHydrant Runbook

FireHydrant has a sophisticated set of response actions for coordinating communications, activities, and retrospectives for incidents that affect your services. Relay helps by automating remediations that involve orchestrating actions across your infrastructure. In this example workflow, an incident that affects an application deployed on Kubernetes can trigger a rollback to a previous version automatically.

Workflow Automation with Human Supervision

IT automation is growing in adoption this year as IT organizations grapple with constantly changing priorities, the pressure of supporting large remote workforces and tight resources. However, IT teams are hesitant to deploy automation workflows on production infrastructure that supports important business applications and services. Trust is an issue – but errors do occur. Unsupervised automation can sometimes create more problems by missing the actual context for issue resolution.

Puppet Agent 7 - SMF provider consistency

Service Management Facility (SMF) is the service management framework for Solaris as of version 10. In previous versions of Puppet, starting a service was effectively the same as enabling it. This meant that the service provider only supported starting and stopping each service. As of Puppet 7, it works the same as any other service provider.

Cloud CI Project

Puppet supports a lot of platforms, including some that aren't well represented in the cloud world, like AIX or Solaris. To cover all these platforms, much of our module testing happened on an internal Jenkins server and our in-house vmpooler infrastructure. This worked pretty well, but had the unfortunate side effect that PRs from community contributors would often get rejected by an opaque process that didn't even tell them what tests failed!

Puppet Agent 7 - Filebucket hash algorithm update

Puppet 7 upgrades the default filebucket hash digest algorithm from MD5 to SHA256, which is generally a good thing. However, this makes upgrades just a little tricky. The mitigation for this is simply to set your digest algorithm to SHA256 on server and agent both before upgrade. Gabriel shows us how to do so in this video.
