Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

@substrate/node-watcher

Long living script that reads from an archive node and loads select information to a Postgresql DB, a.k.a ETL.

The tasks specific to Nomidot are in src/tasks

The script itself lives in nodeWatcher.ts, and anyone can write their own tasks suited to their needs as long as they conform to the Task interface. It is agnostic of what server or db one decides to use.

Instructions to run locally:

  1. Push up the Postgresql and Prisma images: docker-compose up -d
  2. Run the script which populates the database: yarn start

On a Local Kubernetes Cluster (minikube) (writes to CloudSQL)

  1. Start local cluster minikube start
  2. Make sure kubectl is connected to is kubectl cluster-info
  3. Follow same steps as below

On Hosted Google Kubernetes Engine

  1. Mount secrets to nodewatcher pod's volume: kubectl create -f path/to/secrets.yaml
  1. Create namespaces: kubectl create -f path/to/namespace.yaml
  • Make sure you're in the appropriate namespace: kubectl config set-context --current --namespace<namespace>
  • Verify: kubectl config view --minify | grep namespace:
  1. Create nodewatcher deployment: kubectl create -f path/to/nodewatcher_deployment.yaml
  2. Create service: kubectl create -f path/to/service.yaml
  3. Get the nodewatcher deployment IP: kubectl describe deployments nodewatcher
  4. Set PRISMA_ENDPOINT in nomidotwatcher-deployment.yaml to External IP from step 6.
  5. Allow traffic: gcloud compute firewall-rules create allow-nodewatcher-nodeport --allow=tcp:31000

Make a rolling update:

  • Docker Tag the new image(s) docker tag node_watcher_main eu.gcr.io/kusama-etl/node_watcher:v1.0
  • Push it to container registry docker push eu.gcr.io/kusama-etl/node_watcher:v1.0
  • Get the current image name kubectl describe pods ${POD_NAME}
  • Set new deployment image kubectl set image ${current_image} ${new_image}
  • Confirm with kubectl rollout status deployments/${new_image}

PgAdmin into Cloudsql using Proxy

Cloudsql Proxy
  • Make sure Cloudsql Proxy is installed: curl -o cloud_sql_proxy https://dl.google.com/cloudsql/cloud_sql_proxy.darwin.amd64
  • Make it executable: chmod +x cloud_sql_proxy
  • Locate the credentials.json file containing credentials to the service account.
  • Start the proxy: ./cloud_sql_proxy -instances=test-installations-222013:europe-west1:kusama-etl=tcp:0.0.0.0:5432 -credential_file=./key.json
  • It should say something like:
  Listening on 127.0.0.1:5432 for test-installations-222013:europe-west1:kusama-etl
  2020/01/30 17:05:37 Ready for new connections
PgAdmin
  • Get pgadmin: https://hub.docker.com/r/dpage/pgadmin4/

  • Run it: docker run -p 80:80 -e PGADMIN_DEFAULT_EMAIL="[email protected]" -e PGADMIN_DEFAULT_PASSWORD="****" -d dpage/pgadmin4

  • Navigate to localhost:80 in a browser

  • Login with the above credentials

  • Click "New Server"

  • In "Connection" tab, fill in the DB_NAME (e.g. nomidot-node-watcher), DB_USER (e.g. admin), and DB_PASS, as appropriate.

  • Make sure SSL mode is set to Disabled. n.b. "Even though the sslmode parameter is set to disabled, the proxy does provide an encrypted connection."

  • Click Connect.

Port Forwarding

It is also possible to forward our localhost:4467 to our cluster port :4466 with, port forwarding. This will allow us to go to open the GraphQl interface from our local machine.

  1. kubectl get pods --namespace nomidotwatcher-staging
  2. kubectl port-forward --namespace nomidotwatcher-staging <the-pod-name> 4467:4466

Then just go to localhost:4467 in a browser and that will forward your requests to the cluster's 4466 port (where the deployed Prisma server lives).

You can also deploy a new prisma schema by setting the PRISMA_ENDPOINT environment variable to be localhost:4467, and running prisma deploy, e.g. PRISMA_ENDPOINT="http://127.0.0.1:4467" START_FROM="66647" yarn prisma deploy

Updating Kubernetes Job
  1. Make sure you're logged into gcloud with an account that has access to Container Registry. You can also push to Docker Hub but for the sake of having everything in one place, we'll keep it all in GCR. gcloud auth list
  2. Run gcloud auth configure-docker
  3. Check the last build image version with gcloud container images list-tags eu.gcr.io/test-installations-222013/nomidot_watcher
  4. Making sure you're on the appropriate branch, build a new image. docker build -t nomidot_watcher:v1.2.15 . docker build...
  5. Tag that image in the appropraite format for GCR e.g docker tag nomidot_watcher:v1.2.15 eu.gcr.io/test-installations-222013/nomidot_watcher:v1.2.15 docker tag
  6. Push that image with docker push eu.gcr.io/test-installations-222013/nomidot_watcher:v1.2.15 docker push...
  7. Copy the SHA256 hash copy sha...
  8. Paste it into the job config paste sha...
  9. Create the job kubectl create -f /path/to/config.yaml k8 create job
  10. Check it's running kubectl get jobs, kubectl logs -l job-name={jobname} -n nodewatcher-staging k8 check job
  11. Eventually delete the outdated job too kubectl delete jobs old-job-name
