Hardcoding the memory limit seems weird when we already define the limit via kubernetes limits … so making it just use everything available.
# Dockerfile
FROM memcached
ADD start.sh /start.sh
CMD ["sh", "start.sh"]
# start.sh
exec memcached -m $(cat /sys/fs/cgroup/memory/memory.stat |
grep hierarchical_memory_limit |
awk '{print $2 / 1024 / 1024 - 10}')
