This page shows the 2 steps needed to get an LTO Network node up and running using Microsoft Azure, specifically Azure Container Instances (Not to be confused with Azure Kubernetes Services).
So you decided you want to be part of the LTO Network, awesome!
A great way to be part of the community is by actively participating as a node in the network.
Below the 2-step setup procedure using the browser there is an optional procedure for using the command-line interface.
LTO Public Node on Azure — Main screen
As mentioned before we’re configuring a Container instance using ACI. This is not to be confused with AKS, Azure Kubernetes Services. AKS can be used to setup a cluster for container orchestration. This is overkill for what we’re trying to achieve at this time.
Please type “container” (without an s) in the box and “Container instances” will appear. Click Container instances.
LTO Public Node on Azure — Base configuration
First step is to configure some basic settings for your new container instance. You can not really go wrong here. The subscription entry displayed will display on your Azure subscription. You might need to create a Resource group using create new. Please name your container, select a Region where you want to host your container and make sure to enter the image namecorrectly. Before going to the next step we need to change 1 more thing.
LTO Public Node on Azure — Configure memory
Let’s boost the memory a little from 1.5 GB default to 2 GB by clicking Change size. Now click on Next: Networking to go to the next step.
LTO Public Node on Azure — No port / network changes required
Wow, this one is easy. We don’t need to change anything here. Maybe you want to enter the DNS name label. It’s up to you. This is not a requirement. No ports need to be added at this point. You can leave it at default.
Please click Next: Advanced so we can start configuring our node.
LTO Public Node on Azure — Setup your environment variables
Alright at this stage you want to configure your LTO_WALLET_SEED. This is an important step. This should be the seed of the wallet you use for staking. We configure the LTO_WALLET_PASSWORD to encrypt the seed. The LTO_NODE_NAME is the name your node will use to identify itself on the LTO Network.
A future update might include the usage of secrets to secure our configuration.
When you’re done putting in these variables click on Review + create.
LTO Public Node on Azure — Validation passed — Your screen might look slightly different
If validation is successful click Create to create your container and wait for the deployment to finish.
LTO Public Node on Azure — Deployment of Container instance is running
The deployment might take 1–2 minutes to complete.
LTO Public Node on Azure — A successful deployment of your LTO Public Node container on Azure
Your LTO Public Node is now running on Azure using Azure Container Instances. Not convinced? Let’s double check :) Please click on Go to resource.
LTO Public Node on Azure — Connected to the console
Let’s click on Containers under Settings. Now click on Connect and select a bash shell to Connect. A terminal will open. Activate the terminal by clicking on the black screen.
Using the cd (change directory) command we will browse to the /lto/log directory. In this directory you’ll find our logfile called: lto.log.
Start a tail like in the above screenshot and follow the progress as your node downloads the blockchain or maybe is already adding MicroBlocks.
LTO Public Node on Azure — Tailing your Node’s logfile
That’s it. You’ve successfully mastered setting up a LTO Network public node on Microsoft Azure. Awesome!
Depending on your stake (the number of LTO tokens you have in the “2nd wallet”) it will take more or less time for you to start earning LTO. Be patient and be happy. Welcome to the amazing LTO Network community! Read more about community programs.
Optionally you can start your container using the command-line interface. A big advantage of using the CMD is that you can automate everything.
Use the following commands to kick-off your LTO Network Public node using command line:
CONTAINER_WALLET_SEED="SEED1 SEED2 SEED3"
az group create --name $CONTAINER_RESOURCE_GROUP --location $CONTAINER_LOCATION
az container create --resource-group $CONTAINER_RESOURCE_GROUP --name $CONTAINER_NAME \
--image ltonetwork/public-node \
--cpu 1 \
--memory 2 \
--os-type linux \
--ports 80 \
--restart-policy Always \
--environment-variables "LTO_NODE_NAME"="$CONTAINER_NODE_NAME" \
--secure-environment-variables "LTO_WALLET_SEED"="$CONTAINER_WALLET_SEED" "LTO_WALLET_PASSWORD"="$CONTAINER_WALLET_PASSWORD"
With just these two commands you have successfully launched your LTO Network Public node container application. Using the following command you can view your nodes progress:
az container logs --resource-group $CONTAINER_RESOURCE_GROUP --name $CONTAINER_NAME
You can double check your environment variable configuration using the following commands:
az container exec --resource-group $CONTAINER_RESOURCE_GROUP --name $CONTAINER_NAME --exec-command "/bin/bash"
$ echo $LTO_WALLET_SEED
$ echo $LTO_WALLET_PASSWORD
