# redis-overcommit-on-host

Enable overcommitting to memory on a host running a redis container.  See the [Redis documentation](https://redis.io/topics/faq#background-saving-fails-with-a-fork-error-under-linux-even-if-i-have-a-lot-of-free-ram) for more information.

# How to use

Schedule this container to run alongside any host with a running `redis` container.

##### Command line

```sh

docker run https://github.com/bkuhl/redis-overcommit-on-host.git -v /proc/sys/vm:/mnt/vm --privileged

```

##### Docker Compose

```yml

version: '3'

services:

  # redis-overcommit-on-host

  redis-overcommit:

    build: https://github.com/bkuhl/redis-overcommit-on-host.git

    restart: 'no'

    privileged: true

    volumes:

      - /proc/sys/vm:/mnt/vm

  # Your existing Redis service

  redis:

    image: 'redis'

    restart: 'always'

    depends_on:

      - redis-overcommit

```

 

### Why do this in a container?

I'm a big fan of a container's ability to serve as documentation for any special changes that need to happen on the host for a container to run right.
