AWS container service: set max_map_count
I’m trying to run Elasticsearch on AWS container service. Here the documentation that I’m following: https://www.elastic.co/guide/en/elasticsearch/reference/current/docker.html#docker-cli-run-prod-mode
The vm_map_max_count setting should be set permanently in
What are the differences between Kubernetes Pods and Docker Compose(s) (Composures?) Docker compose wait for without sleep command When does Docker write to iptables? How to mount a docker volume while using a windows host? Getting Docker linked containers localhost pointing to host localhost Alternatives to debug a docker + gunicorn app in production
$ grep vm.max_map_count /etc/sysctl.conf
To apply the setting on a live system type: sysctl -w
Is there any way to set the vm.max_map_count via script? I don’t want to do it manually every time I run a new container.

You could still set it permanently in /etc/sysctl.conf as per you’ve mentioned in your Q. Didn’t it work?
as per this ticket you could set it up as follows:
sysctl -qw vm.max_map_count=65535
Hope it helps!
I found a solution:
- create an empty container
- Launch an EC2 inside the previous container: http://docs.aws.amazon.com/AmazonECS/latest/developerguide/launch_container_instance.html
- Add the user data (http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/user-data.html) as follow:
#!/bin/bash echo vm.max_map_count=262144 >> /etc/sysctl.conf sysctl -w vm.max_map_count=262144
Now the EC2 instance is properly configured.
