Installation Confirmation - dApp

1. Install docker run --name=doichain-<your-host> --hostname=doichain-<your-host> -it --rm -e DAPP_CONFIRM='true' -e DAPP_VERIFY='true' -e DAPP_SEND='true' -e RPC_USER='admin' -e RPC_PASSWORD='<your-password>' -e RPC_HOST=localhost -e DAPP_HOST=<dAppHostFromTheInternet:Port> -e DAPP_SMTP_HOST=<smtp-host> -e DAPP_SMTP_USER=<smtp-username> -e DAPP_SMTP_PASS=<smtp-password> -e DAPP_SMTP_PORT=25 -p 3000:3000 -p 8338:8338 -v doichain.org:/home/doichain/data doichain/dapp:latest

2. Update the DNS of your mail domain(s) :

   1. Connect to your running docker container via docker ps and docker attach <your-cointainer>
   2. list your accounts with doichain-cli listaccounts
   3. get the account address of your account doichain-cli getaccountaddress "" or use:doichain-cli getaddressesbyaccount ""
   4. get the pubkey from doichain-cli validateaddress <your-address>
   5. add a TXT field doichain-opt-in-provider:<your-email-domain e.g. doichain.org>
   6. add a TXT field doichain-opt-in-key:<your pubkey from above>
   7. exit your docker cointainer
   8. start docker container again with an additional environment variable -e CONFIRM_ADDRESS=<your-address> (or modify `/home/doichain/data/dapp/settings.json ``) which is the address of you found under 2.3

3. check if your blockchain receive blocks with: doichain-cli getblockcount

4. check your balance with doichain-cli getbalance (send some coins with doichain-cli sendtoaddress )

Installation Verify - dApp

2. docker run --name=doichain-<your-host> --hostname=doichain-<your-host> -it --rm -e DAPP_CONFIRM='true' -e DAPP_VERIFY='true' -e DAPP_SEND='true' -e RPC_USER='admin' -e RPC_PASSWORD='<rpc-password>' -e RPC_HOST=localhost -e DAPP_HOST=<dAppHostFromTheInternet:Port> -e DAPP_SMTP_HOST=<smtp-host> -e DAPP_SMTP_USER=<smtp-username> -e DAPP_SMTP_PASS=<smtp-password> -e DAPP_SMTP_PORT=25 -p 3000:3000 -p 8338:8338 -v doichain.org:/home/doichain/data doichain/dapp:latest

Pitfalls and possible errors

1. Authentication of dApp (REST-API) needs correct auth token and user id. Get it and correct authentication!
2. Doi gets successful accepted by REST interface and appears in the dapps web frontend but nothing else happens. (connect to the docker container and check for errors) 2.2 no coins in the wallet - get some fund and send to an address of your dApp in send mode 2.3 configure mail account (mail server, username, password) server for confirm dapp
3. confirmation link shows localhost and not correct url of dapp (e.g. http://dapp.doichain.org)
4. DOI-Request Email doesn't loook beatiful or should look differently. Please change template and data in server/api/rest/imports/debug.js
5. DOI-Request Email has wrong sender email address. Please change template and data in server/api/rest/imports/debug.js
6. Confirmation email is not send out. Enable type 'confirm' (and maybe 'verify') in /home/doichain/data/dapp/settings.json

2. shutdown your old docker container (docker stop )
3. create doinet on docker ``docker network create doinet```
4. start mongo (see: https://hub.docker.com/_/mongo) (change the password!) docker run -d --network doinet --name mongo
   -e MONGO_INITDB_ROOT_USERNAME=doichain
   -e MONGO_INITDB_ROOT_PASSWORD=secret
   mongo
5. start a new docker container based on version 0.0.9 (e.g. use makefile provided make mainnet_<your-new-doichain-node-name>
