# e2-micro has less than 1 GiB RAM. The upstream image defaults to
# -Xmx768m, which can starve sshd/Docker/guest-agent. Keep this
# configurable, but use a safer default for the current VM.
- JAVA_HEAP_SIZE=${JAVA_HEAP_SIZE:-512}
# 384 MiB was stable in the recovery smoke check: it leaves
# room for the guest OS and prevents the Gateway UI from being killed
# before the login dialog can report a broker-side failure. Operators can
# still set JAVA_HEAP_SIZE explicitly for a larger VM.
- JAVA_HEAP_SIZE=${JAVA_HEAP_SIZE:-384}
# The upstream vmoptions use 20 parallel GC threads, which is too
# aggressive for the current 2 vCPU VM and can slow Gateway startup.
