# Docker images for OpenRAM #
## Installing Docker ##
There are a number of ways to install Docker. Pick your favorite.
* On Mac from docker.com with .app:
https://docs.docker.com/docker-for-mac/install/
* On Windows from docker.com:
https://docs.docker.com/docker-for-windows/install/
* On Ubuntu:
https://docs.docker.com/install/linux/docker-ce/ubuntu/
NOTE: If you plan to use a VPN, do *NOT* use the Docker Toolbox for
Mac or the docker from [Macports](https://www.macports.org/
"Macports") as these require a network socket that breaks when you
install some VPN software. To understand the difference, check out [this
page](https://docs.docker.com/docker-for-mac/docker-toolbox/).
## Running Docker ##
### Terminal only ###
* To run as a generic user:
```
make mount
```
## Updating the image ##
If there are updates to the image, you can pull a new one from the hub with:
```
make pull
```
This is not automatically done, so if you have a problem, make sure you are up-to-date.
## Building your own image ##
You can run the build script to build a local image:
```
make build
```
If you want to change things, modify the openram-ubuntu/Dockerfile and let me know what should be fixed.
