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
/etc/sysctl.conf:

$ grep vm.max_map_count /etc/sysctl.conf

vm.max_map_count=262144

To apply the setting on a live system type: sysctl -w
vm.max_map_count=262144

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.

Thanks

I found a solution:

1. create an empty container
2. Launch an EC2 inside the previous container: http://docs.aws.amazon.com/AmazonECS/latest/developerguide/launch_container_instance.html
3. Add the user data (http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/user-data.html) as follow:

Default

#!/bin/bash echo vm.max_map_count=262144 >> /etc/sysctl.conf sysctl -w vm.max_map_count=262144

1 2 3 4

#!/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.
