Running a laconicd fixturenet with console

The following tutorial explains the steps to run a laconicd fixturenet with CLI and web console that displays records in the registry. It is designed as an introduction to Stack Orchestrator and to showcase one component of the Laconic Stack. Prior to Stack Orchestrator, the following 4 repositories had to be cloned and setup manually:

Now, with Stack Orchestrator, it is a few quick commands. Additionally, the docker and docker compose integration on the back-end allows the stack to easily persist, facilitating workflows.

Setup laconic-so

To avoid hiccups on Mac M1/M2 and any local machine nuances that may affect the user experience, this tutorial is focused on using a fresh Digital Ocean (DO) droplet with similar specs: 16 GB Memory / 8 Intel vCPUs / 160 GB Disk.

ssh root@IP

Get the install script, give it executable permissions, and run it:

curl -o install.sh https://raw.githubusercontent.com/cerc-io/stack-orchestrator/main/scripts/quick-install-linux.sh

chmod +x install.sh

bash install.sh

Confirm docker was installed and activate the changes in ~/.profile:

docker run hello-world

source ~/.profile

Verify installation:

laconic-so version

Setup the laconic fixturenet stack

Get the repositories

laconic-so --stack fixturenet-laconic-loaded setup-repositories --include git.vdb.to/cerc-io/laconicd,git.vdb.to/cerc-io/laconic-sdk,git.vdb.to/cerc-io/laconic-registry-cli,git.vdb.to/cerc-io/laconic-console

Set this environment variable to the Laconic self-hosted Gitea instance:

export CERC_NPM_REGISTRY_URL=https://git.vdb.to/api/packages/cerc-io/npm/

Build the containers:

laconic-so --stack fixturenet-laconic-loaded build-containers

It's possible to run into an ESOCKETTIMEDOUT error, e.g., error An unexpected error occurred: "https://registry.yarnpkg.com/@material-ui/icons/-/icons-4.11.3.tgz: ESOCKETTIMEDOUT". This may happen even if you have a great internet connection. In that case, re-run the build-containers command.

Set this environment variable to your droplet's IP address:

export LACONIC_HOSTED_ENDPOINT=http://<your-IP>

Deploy the stack:

laconic-so --stack fixturenet-laconic-loaded deploy up

Check the logs:

laconic-so --stack fixturenet-laconic-loaded deploy logs

You'll see output from laconicd and the block height should be >1 to confirm it is running:

Confirm operation of the registry CLI:

laconic-so --stack fixturenet-laconic-loaded deploy exec cli "laconic cns status"

{

Configure Digital Ocean firewall

Let's open some ports.

In the Digital Ocean web console, navigate to your droplet's main page. Select the "Networking" tab and scroll down to "Firewall".
Get the port for the running console:

echo http://IP:$(laconic-so --stack fixturenet-laconic-loaded deploy port laconic-console 80 | cut -d ':' -f 2)

http://IP:32778

Go back to the Digital Ocean web console and set an Inbound Rule for Custom TCP of the above port:

32778 in this example, but yours will be different.
do the same for port 9473

Additional ports will need to be opened depending on your application. Ensure you add your droplet to this new Firewall and wait a minute or so for the update to propagate.

Navigate to http://IP:port and ensure laconic-console is functioning as expected:

ensure you are connected to laconicd; no error message should pop up;
the wifi symbol in the bottom right should have a green check mark beside it
navigate to the status tab; it should display similar/identical information
navigate to the config tab, you'll see something like (with your IP):

wns
  webui http://68.183.195.210:9473/console
  server http://68.183.195.210:9473/api

Publish and query a sample record to the registry

The following command will create a bond and publish a record:

laconic-so --stack fixturenet-laconic-loaded deploy exec cli ./scripts/create-demo-records.sh

You'll get an output like:

Balance is: 99998999999999998999600000
Created bond with id: dd88e8d6f9567b32b28e70552aea4419c5dd3307ebae85a284d1fe38904e301a
Published demo-record-1.yml with id: bafyreierh3xnfivexlscdwubvczmddsnf46uytyfvrbdhkjzztvsz6ruly

The sample record we deployed looks like:

record:
  type: WebsiteRegistrationRecord
  url: 'https://cerc.io'
  repo_registration_record_cid: QmSnuWmxptJZdLJpKRarxBMS2Ju2oANVrgbr2xWbie9b2D
  build_artifact_cid: QmP8jTG1m9GSDJLCbeWhVSVgEzCPPwXRdCRuJtQ5Tz9Kc9
  tls_cert_cid: QmbWqxBEKC3P8tqsKc98xmWNzrzDtRLMiMPL8wBuTGsMnR
  version: 1.0.23

Return to the laconic-console

the published record should now be viewable
explore it for more information
click on the link that opens the GraphQL console
the query is pre-loaded, click the button to run it
inspect the output

Try out additional CLI commands

these are documented here and updates are forthcoming
e.g,:

laconic-so --stack fixturenet-laconic-loaded deploy exec cli "laconic cns record list"
