Amazon Lambda compute in Amazon CodeBuild
Amazon Lambda compute offers optimized start-up speeds for your builds. Amazon Lambda supports faster builds due to a lower start-up latency. Amazon Lambda also automatically scales, so builds aren’t waiting in queue to run. However, there are some use-cases which Amazon Lambda does not support, and if they impact you, use the EC2 compute. For more information, see Limitations of Amazon Lambda compute.

Limitations of Amazon Lambda compute
There are some use-cases which Amazon Lambda does not support, and if they impact you, use the EC2 compute:
-
Amazon Lambda doesn't support tools that require root permissions. For tools such as
yum
orrpm
, use the EC2 compute type or other tools that don't require root permissions. -
Amazon Lambda doesn't support Docker builds or runs. You can use alternatives that don’t require root permissions, such as Podman.
-
Amazon Lambda doesn't support writing to files outside
/tmp
. The included package managers are configured to use the/tmp
directory by default for downloading and referencing packages. -
Amazon Lambda doesn't support the environment type
LINUX_GPU_CONTAINER
and isn't supported on Windows Server Core 2019. -
Amazon Lambda doesn't support caching, batch builds, custom build timeouts, queue timeout, build badges, privileged mode, custom runtime environments, or runtimes longer than 15 minutes.
-
Amazon Lambda doesn't support VPC connectivity, a fixed range of CodeBuild source IP addresses, EFS, semantic versioning, installing certificates, or SSH access with Session Manager.
