Five Things To Know About Bottlerocket, AWS’ New Container-Optimized Linux

Joseph Tsidulko

AWS introduced Bottlerocket to power containerized workloads running on its own managed container services, and everywhere else.

The Lightweight Linux Landscape

Bottlerocket’s development was motivated by a similar logic that went into building Amazon Linux, a distribution that took advantage of native AWS feature around security, orchestration and monitoring.

“This is kind of a redux of that stuff,” Ulander said.

But Bottlerocket isn’t the first Linux built for containers.

CoreOS, acquired by Red Hat in 2018, was a pioneer in the category, and other options include Alpine, RancherOS, and Talos.

Those are all good products, Ulander said.

What makes Bottlerocket stand out from that pack, he said, is its ability to hook into native AWS managed container services—EKS and ECS.

“The differences between similar container operating systems and Bottlerocket is that Amazon has optimized it to perform on AWS and integrate with other AWS services,” said Brady Thompson, a solutions architect at Austin, Tex.-based AWS channel partner Flux7, an NTT DATA company.

And there are other differences, especially around security and upgradability features, Thompson said.

Other lightweight Linux distributions “are all very minimal, meaning they will ship with only the absolute required software to run containersy,” Thompson told CRN.
