Add Dockerfile

I have included a commit that adds a github workflow for building and pushing images to dockerhub. For that to actually work we'd need to:

1. create a dedicated "machine" user on our dockerhub inputoutput organisation
2. have devops manage the credentials
3. create an API token on dockerhub for that user
4. add the credentials to secrets in this repository settings (using the variable names DOCKERHUB_USERNAME and DOCKERHUB_TOKEN)

I think this is low-effort and should be tried out. Otherwise I'll remove the commit.

I managed to produce image :

pawel@pure:~/Work/IOHK/cardano-transactions (hasufell/ADP-290/create-docker-image)$ docker build --tag  cardano-transactions .
....

Also was able to invoke the stuff:

pawel@pure:~/Work/IOHK/cardano-transactions (hasufell/ADP-290/create-docker-image)$ docker run --rm -ti 450c03d71cea empty 764824073
-----BEGIN CARDANO TX-----
version: 1.0.0
Gi2WSgmf/5//
-----END CARDANO TX-----

But had problem when adding the rest, for example:

pawel@pure:~/Work/IOHK/cardano-transactions (hasufell/ADP-290/create-docker-image)$ docker run --rm -ti 450c03d71cea empty 764824073 \
> | cardano-tx add-input 0 3b40265111d8bb3c3c608d95b3a0bf83461ace32d79336579a1939b3aad1c0b7
cardano-tx: command not found
write /dev/stdout: broken pipe

OR

pawel@pure:~/Work/IOHK/cardano-transactions (hasufell/ADP-290/create-docker-image)$ docker run --rm -ti 450c03d71cea empty 764824073 \
> | add-input 0 3b40265111d8bb3c3c608d95b3a0bf83461ace32d79336579a1939b3aad1c0b7
add-input: command not found
write /dev/stdout: broken pipe

@hasufell maybe I am doing something wrong when running docker image? I also tried :

pawel@pure:~/Work/IOHK/cardano-transactions (hasufell/ADP-290/create-docker-image)$ docker run --rm -ti 450c03d71cea empty 764824073 \
> | docker run --rm -ti 450c03d71cea add-input 0 3b40265111d8bb3c3c608d95b3a0bf83461ace32d79336579a1939b3aad1c0b7
the input device is not a TTY
write /dev/stdout: broken pipe

Nevertheless, would be good to add instructions how to built and run an example in README.md

[paweljakubas]

Now works for me:

pawel@pure:~/Work/IOHK/cardano-transactions (hasufell/ADP-290/create-docker-image)$ docker run --rm -ti --entrypoint sh cardano-transactions
/ # cardano-tx empty 764824073 \

@KtorZ @rvl so from my user perpective I confirm it works fine. I was able to build locally and use it. The image is very small 4.04mb which is awesome. When it comes to whether other parts (devops, deployment, etc) are correct/as should be I leave those considerations to you

[paweljakubas]

Now image doubled in size, although still very small:

pawel@pure:~/Work/IOHK/cardano-transactions (hasufell/ADP-290/create-docker-image)$ docker images
REPOSITORY                 TAG                 IMAGE ID            CREATED             SIZE
cardano-tx                 latest              572c49fc00ee        3 minutes ago       8.38MB

Contener works:

pawel@pure:~/Work/IOHK/cardano-transactions (hasufell/ADP-290/create-docker-image)$ docker run --rm -ti --entrypoint sh cardano-tx
/ # cardano-tx empty 764824073 \
