Small footprint datadog-agent based on Alpine Linux

system-probe is no longer built for datadog-agent-alpine images.Use official image if you usesystem-probe.

Availability ofprocess-agent,security-agent, andtrace-agent can be switched by the make arguments:ENABLE_PROCESS_AGENT,ENABLE_SECURITY_AGENT,ENABLE_TRACE_AGENT (set1 to enable)

Installed integrations can be selected byINTEGRATIONS_CORE argument.btrfs,disk,ssh_check,statsd,system_core,system_swap are enabled by default.

For example, following command will build the Alpine based image withprocess-agent andtrace-agent.

make docker-build ENABLE_TRACE_AGENT=1

The image works basically same as the official datadog-agent image.For some reason, this image requiresseccomp orapparmor setting to usejournald integration.

# docker-compose.ymlsecurity_opt:      -"apparmor:unconfined"      -"seccomp:unconfined"

docker run --security-opt=seccomp=unconfined --security-opt=apparmor=unconfined ...

Pre-built images with some combination of the features are available on GitHub Container Registry.
