Prerequisites
- install taskfile:
npm install -g @go-task/cli
Running the examples with Taskfile
cdinto the directory underexamplesthat has theTaskfile.yml, e.g. (from solo repo root directory)cd examples/network-with-block-node/- make sure that your current kubeconfig context is pointing to the cluster that you want to deploy to
- run
taskwhich will do the rest and deploy the network and take care of many of the pre-requisites
NOTES:
- Some of these examples are for running against large clusters with a lot of resources available.
- Edit the values of the variables as needed.
Customizing the examples
- take a look at the Taskfile.yml sitting in the subdirectory for the deployment you want to run
- make sure your cluster can handle the number in SOLO_NETWORK_SIZE, if not, then you will have to update that and make it match the number of nodes in the
init-containers-values.yaml:hedera.nodes[] - take a look at the
init-containers-values.yamlfile and make sure the values are correct for your deployment with special attention to:- resources
- nodeSelector
- tolerations
