How to use docker and docker-compose for iroha development

Advantages:

  • usage of docker-compose allows folder iroha to be mounted into container. This allows you to change code in host machine, at the same time changing it inside container(s)
  • very easy to start development without dependencies conflicts

Note: permissions and ownership will be transfered 1-to-1 from host to container and backwards. It means, that file owned by user:user (id=1000) will be owned inside container by some other user (probably the same) with id=1000.

It means, that file created inside container by root will be owned by root on the host!

First of all, you should clone iroha repository with all submodules to your host machine:

git clone --recursive https://github.com/hyperledger/iroha
cd iroha

Then, build iroha-dev image using latest docker-compose 1:

docker-compose build

Run container:

docker-compose run iroha-dev bash

You got shell access into container with all dependencies for iroha. To build iroha, go to $IROHA_HOME folder and run build.sh2:

cd $IROHA_HOME
./build.sh

If you want to remove container for some reason, use 1:

docker-compose down

How to use docker and docker-compose for production

Footnotes

  1. You must be in the same folder with docker-compose.yml file. ↩ ↩2

  2. build.sh must be executed from $IROHA_HOME direcory inside docker container. ↩
