+# Docker Bomb Images : mem
+
+Simple container used to bomb mem usage for crash testing. !!! WARNING, starting this container will start flooding your mem by default for 10sec.
+
+You can find information on this image and how to use it by visiting the [Dockerhub registry](https://github.com/startxfr/docker-images)
+
+| [](https://travis-ci.org/startxfr/docker-images) | [Dockerhub Registry](https://hub.docker.com/r/startx/openshift-bomb-mem) | [Sources](https://github.com/startxfr/docker-images/Bombs/) | [STARTX Profile](https://github.com/startxfr) |
+|-------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------|----------------------------------------------------------------------|-----------------------------------------------|
+
+## Running from dockerhub registry
+
+* with `docker` you can run `docker run -it --name="centos" startx/openshift-bomb-mem` from any docker host
+* with `docker-compose` you can create a docker-compose.yml file with the following content
+```
+fedora:
+ image: startx/openshift-bomb-mem:latest
+ container_name: "os-ocp-bomb-mem"
+ environment:
+ CONTAINER_TYPE: "bomb"
+ CONTAINER_SERVICE: "mem"
+ CONTAINER_INSTANCE: "os-ocp-bomb-mem"
+```
+
+## Using this image in your own container
+
+You can use this Dockerfile template to start a new personalized container based on this container
+ ```
+FROM startx/openshift-bomb-mem:latest
+#... your container specifications
+CMD ["/bin/sx"]
+```
+
+## Environment variable
+
+| Variable | Type | Mandatory | Description |
+|---------------------------|----------|-----------|--------------------------------------------------------------------------|
+| CONTAINER_INSTANCE | `string` | `yes` | Container name. Should be uning to get fine grained log and application reporting
+| CONTAINER_TYPE | `string` | `no` | Container family (os, service, application. could be enhanced
+| CONTAINER_SERVICE | `string` | `no` | Define the type of service or application provided
+| HOSTNAME | `auto` | `auto` | Container unique id automatically assigned by docker daemon at startup
+| TEST_DURATION | `seconds`| `auto` | Running test duration (defautl = 10sec)
+
+
+## For advanced users
+
+You you want to use this container and code to build and create locally this container. You can follow theses instructions to setup and working environment.
+
+This section will help you if you want to :
+* Get latest version of this container Bombs
+* Enhance container content by adding instruction in Dockefile before build step
+
+You must have a working environment with the source code of this repository. Read and follow [how to setup your working environment](https://github.com/startxfr/docker-images#setup-your-working-environment-mandatory) to get a working directory. The following instructions assume you are at the top level of your working directory.
+
+### Build & run a container using `docker`
+
+1. Jump into the container directory with `cd Bombs/mem`
+2. Build the container using `docker build -t bomb-mem .`
+3. Run this container
+ 1. Interactively with `docker run -it bomb-mem`. If you add a last parameter (like `/bin/bash`) to will run this command instead of the default entrypoint. Usefull to interact with this container (ex: `/bin/bash`, `/bin/ps -a`, `/bin/df -h`,...)
+ 2. As a daemon with `docker run -d bomb-mem`
+
+
+### Build & run a container using `docker-compose`
+
+1. Jump into the container directory with `cd Bombs/mem`
+2. Run this container
+ 1. Interactively with `docker-compose up` Startup logs appears and escaping this command stop the container
+ 2. As a daemon with `docker-compose up -d`. Container startup logs can be read using `docker-compose logs`
