# dockerfiles

All the Dockerfiles I use for various purposes. More detailed usage instructions

are at the top of each Dockerfile.

## Methodology

In general I like to build all-in-one Dockerfiles for things like general

software development and I like to use docker-compose for production

environments so that things like databases, caching, media storage, workers,

and web hosts are split into their own containers.

## Multiline

I don't like having a lot of files that I `COPY` around and prefer writing

multiline echos and sed commands to create and adjust configuration files. When

heredocs are widely supported and not just in labs I plan on using that.

## Containers all the way down

You'll notice that I have some commands laying around that look something like:

    docker run -it --rm -v /var/run/docker.sock:/var/run/docker.sock alpine \

      sh -c "apk add docker curl && curl -o- https://raw.githubusercontent.com/overshard/dockerfiles/master/webdev/backup.sh | sh"

This runs a docker container that then does a curl command to then run a script

that runs more docker containers. I like to keep all my scripts and code based

on containers and be as multi-platform as possible. I use Linux, MacOS, and

Windows daily and the only way to make things work on all platforms is to just

run everything in containers and have docker installed everywhere.

I also really don't like batch and powershell scripts on Windows and prefer to

just use shell scripts for everything.

## Quick container

I sometimes setup a quick container to do test things on with:

    docker run -td --restart unless-stopped --name alpine \

        -v "/var/run/docker.sock:/var/run/docker.sock" \

        alpine ash

Then you can enter it at anytime with:

    docker exec -it alpine ash

## Backup volumes

To copy data from a container to the host system while using docker volumes you

can run something like this:

    docker run --rm --volumes-from bythewood -v "${pwd}:/data" alpine \

        tar --exclude .venv --exclude node_modules --exclude media --exclude db.sqlite3 \

        -zcvf /data/bythewood-`date +%Y-%m-%d`.tar.gz /home/dev/.ssh /home/dev/code

**NOTE:** Instead of using ${pwd} you can also use a full path, on Windows it'd

look something like `"/C/Users/Isaac Bythewood/Documents/Backups:/data"`. The

double quotes are important to prevent errors and use spaces in the path.

## Volume location on Windows

You can easily get to docker volumes on Windows by typing the following in

Explorer:

    \\wsl$\docker-desktop-data\data\docker\volumes
