I'm running docker for mac and I'm using a docker file. I'm also using a docker-compose file to create a mysql docker instance and a sam local instance on the same bridge network.
I was able to copy over my files to the sam local instance and get the mysql instance up and running.
When I do a docker-compose --build
I get the following error when I hit any endpoint on the API: Error invoking nodejs6.10 runtime: Error response from daemon: Minimum memory limit allowed is 4MB
when I execute this using sam local without the docker-compose or docker files inside of just my project folder. I don't get this issue.
From what I can tell, this comes from the underlying linux vm that docker for mac runs. These containers are LXC containers and they require a minimum memory of 4mb.
If I run this image using:
docker run -it --memory-reservation 10000000 -v /var/run/docker.sock:/var/run/docker.sock -p 3000:3000 samlocal
I still get this issue, which is what leads me to believe this is an issue in instantiating new lambda containers within sam local.
I'm not sure if there is a way to modify the hostconfig file for LXC from within the container or if there is some other solution to this problem.
My samlocal dockerfile and docker-compose file's follow:
