Migrate and new packages

With Metamask (chrome)- go to Settings/Security/Reveal pass phrase words and set MNENOMIC to the passphase: export MNENOMIC="blat"

yarn deploy:kovan yarn deploy:rinkeby yarn deploy:main

Create local ganache docker image:

Update the local ganche-docker blockchain:

sudo docker ps export contid="your Container ID" sudo docker exec -it $contid ls sudo docker exec -it $contid tar -zcvf data.tar.gz ./data/ sudo docker cp $contid:/app/data.tar.gz /home/w/workspace/contracts/

w@x1:/workspace/contracts/data$ mv data data_old w@x1:/workspace/contracts/data$ tar -xvzf data.tar.gz

mv ./data ./data-sik; mkdir ./data; yarn testrpcdata & yarn deploy:local

sudo docker login registry.gitlab.com/cash36/contracts sudo docker build -t registry.gitlab.com/cash36/contracts:latest . sudo docker push registry.gitlab.com/cash36/contracts:latest

yarn networks > networks.md

Check in contrats and merge master which creates a new tag in gitlab and deployment of the package on github

Add new version to package.json:

  • cash36-admin-frontend
  • cash36-frontend
  • cash36-compliance
  • cash36-exchange

And rebuild dependencies and stubs (eventually set NPM_TOKEN=...2bb)

( cd cash36-admin-frontend; git pull; nvm use lts/dubnium; yarn; ) ( cd cash36-frontend; git pull; nvm use lts/dubnium; yarn; ) ( cd cash36-exchange; git pull; nvm use lts/dubnium; gradle build; gradle genToken36Controller genCash36Exchange ;gradle test ) ( cd cash36-compliance; git pull; nvm use lts/dubnium; gradle build; gradle genCash36Compliance genCash36Company; gradle test )

Push & merge to master to create new docker images, test local installation with cd cash36-docker docker-compose up
