NEM NIS Docker node setup

NIS - NEM Infrastructure Server

The NEM Infrastructure Server (short: NIS) was written in Java. It allows you interact with NEM.

Let's start

For rapid development, NEM officially offers a helper script file to automatically deploy docker container. If you insist on setup docker manually, here is reference. Below is tutorial of using helper script:

  1. Download script first
mkdir nem-dev
cd nem-dev
curl -q https://raw.githubusercontent.com/rb2nem/nem-dev-guide/master/docker/ndev > ndev
chmod +x ndev
  1. Execute script
$ ./ndev

The first time you run the script, it will:

  • check if its settings.sh file exists, and create it if needed. The user is prompted for values to be provided.
  • check if the required docker-compose.yml file is present, and download it from github if needed
  • Download docker images from the DockerHub

To check that the containers are running:

$ ./ndev --status

It will print: status

And open a shell in the NIS container:

$ ./ndev -c nis bash

bash

In container shell, check if NIS is running:

[root@23627cb63be0 /]# ps aux

This shows that NIS is running (this is the java -Xms512M -Xmx1G ... process).

psaux

If not, type below command:

[root@23627cb63be0 /]# supervisorctl start nis

You can access the logs of NIS with tail /var/log/nis-stderr.log -f:

[root@23627cb63be0 /]# tail /var/log/nis-stderr.log -f

NIS

If you see that the NIS instance is communicating with other instances (synchronizing with Node [Hi, I am MedAlice2...) which means our NIS instance is synchronized ongoing. You can start to interact with NEM through NEM-SDK now.
