This very modest PR allows String values for docker_container memory attribute.
Currently, the docker_container resource only allows
Fixnum
values for the attribute (in other words, memory value is implicitly in bytes) but the docker documentation says that thedocker run --memory
parameter supports optional units. It is also possible to specify different memory and memory+swap limits.With this PR I can set
docker.memory = '1G'
ordocker.memory = '150m,200m'
, while still allowing for Fixnum memory values as before.
