📦 Pre-Installation Steps

⚠️ MyDexChain is fully docker compatible and please follow Windows, Centos, Ubuntu, Amazon Linux, MAC OS installation steps before running MyDexChain Node. After docker installation open a command line || terminal and run command to check the docker version.

docker -v

Output: Docker version 20.10.0, build 7287ab3

Mydexchain Node Offline Sync (Fastest Way)

To catchup block syncs we publish blocks in zipped format. You can download block archives and catchup quickly. This way is usefull for clean node deployements .

[Quick sync is only possible on initial setup. Do not use this way for current nodes.]

Steps:

• Start the node to trigger initial Database Schemas.
• Download the archive.
• Unzip files to docker volume.
• Start the node

Offline Blocks Link: https://backup.mydexchain.io

Commands to Execute:

wget https://backup.mydexchain.io/data-[date].tar.gz

Stop mydexchain node

docker kill mydexchain

Delete old data dir

rm -rf /var/lib/docker/volumes/mydexchain/_data/12

Untar archive to data dir

tar -zxvf data-[date].tar.gz -C /var/lib/docker/volumes/mydexchain/_data/

And start the node

docker run -d --rm -p 2020:2020 -p 2053:3030 -v mydexchain:/var/lib/postgresql/ --privileged --log-driver=none --name mydexchain mydexchain/mydexchain:latest

💻 Usage

1. Run MyDexChain:

MyDexChain docker file is stored in dockerhub and ready for use with command: (Please check the version and use as tag rather than latest)

docker run -d --rm -p 2020:2020 -p 2053:3030 -v mydexchain:/var/lib/postgresql/ --privileged --log-driver=none --name mydexchain mydexchain/mydexchain:latest

After docker container comes up run the command;

docker ps

Output: db641c6c55b7 mydexchain/mydexchain "/startup.sh" 32 seconds ago Up 31 seconds 0.0.0.0:2020->2020/tcp, 5432/tcp mydexchain

📚 FAQ

How Can I Calc Fee

Sample Fee Calculation

Transaction Amount	Fee %	Fee Amount
1000	0.003	3.00
10000	0.0003	+2.70
100000	0.00003	+2.70
1000000	0.000003	+2.70
10000000	0.0000003	+2.70
100000000	0.00000003	+2.70
1000000000	0.000000003	+2.70
10000000000	0.0000000003	+2.70
100000000000	0.00000000003	+2.70
		24.60

25000 myDexChain Transaction = (1000 x 0.003) + (9000 x 0.0003) + (15000 x 0.00003) = 6.150 Fee

Common Problems

These options are settings that change shell behavior. The following table is a list of options that might be useful to you:

Check	How
Cannot connect to the Docker daemon. Is the docker daemon running on this host?	Check your docker service is up and running.
Block Sync is not working	Check your internet connectivity.

How to Backup the MyDexChain Node?

MyDexCahin maps blocks inside PostgreSQL and it has been addressed inside dockerfile. All the data is saved inside /var/lib/docker/volumes/mydexchain and make sure that you backup the folder.

Linux & MacOs

1. Stop MyDexChain Node Docker Container (For Data Consistency):

docker kill mydexchain

2. Copy /var/lib/docker/volumes/mydexchain to Backup Path:

rsync -avzhHP /var/lib/docker/volumes/mydexchain/ /backup_path/mydexchain/

3. Start MyDexChain Docker Container on the New Docker Host :

docker run -d --rm -p 2020:2020 -p 2053:3030 -v mydexchain:/var/lib/postgresql/ --privileged --log-driver=none --name mydexchain mydexchain/mydexchain:latest

4. Follow the Blocks :

docker attach mydexchain

Windows

1. Stop MyDexChain Node Docker Container (For Data Consistency):

docker kill mydexchain

2. Copy %USERPROFILE%\AppData\Local\Docker\wsl\data\ext4.vhdx to Backup Path:

3. Start MyDexChain Docker Container on the New Docker Host :

docker run -d --rm -p 2020:2020 -p 2053:3030 -v mydexchain:/var/lib/postgresql/ --privileged --log-driver=none --name mydexchain mydexchain/mydexchain:latest

4. Follow the Blocks :

docker attach mydexchain

How to Migrate the MyDexChain Node to Another Docker Host?

⚠️ Before migrating your node be sure that docker is installed on target.

Linux & MacOs

1. Stop MyDexChain Node Docker Container:

docker kill mydexchain

2. Copy Node Files to New Docker Host :

rsync -avzhHP --rsync-path="sudo rsync" -e "ssh -i key -o StrictHostKeyChecking=no" /var/lib/docker/volumes/mydexchain/ root@target_ip:/var/lib/docker/volumes/mydexchain/

3. Start MyDexChain Docker Container on the New Host :

docker run -d --rm -p 2020:2020 -p 2053:3030 -v mydexchain:/var/lib/postgresql/ --privileged --log-driver=none --name mydexchain mydexchain/mydexchain:latest

Where is the Pyhsical Path Docker Mount Volume Located in Windows OS?

Mount disk is located under:

%USERPROFILE%\AppData\Local\Docker\wsl\data\ext4.vhdx

How to run Test Mode

Test mode is used for making demo for DexChain Network. Do not use for production!

docker run -d --rm -p 2020:2020 -p 2053:3030 -v mydexchain:/var/lib/postgresql/ --privileged --log-driver=none --name mydexchaintestnet mydexchain/mydexchain:testnet
