Released on 23rd July 2021

  • (UI) Dockerfile now uses node:14.
  • (UI) Fixed some security vulnerabilities.

Update Instructions

To update an instance of PANIC to this version, run these commands inside the project directory:

git fetch                # Fetch these changes
git checkout v2.4.0      # Switch to this version

# At this stage, you should stop the alerter and the UI

pipenv sync              # Update dependencies

The next step is to make sure that you are running version 1.29.1 of the Polkadot API Server, this is important as otherwise PANIC won't be able to retrieve data.

When you have done all of the above follow one of the guides below depending on whether you were running PANIC from source, or using docker-compose.

Running from Source

Restart the UI

Start by navigating into the the UI directory and install the packages defined in package.json:

cd src/web/ui
npm ci --only=production    # use sudo in linux if necessary

Re-build the UI, re-direct to the PANIC Polkadot directory, and start the UI

npm run-script build     # use sudo in linux if necessary
cd ../../../
bash run_ui_server.sh
Restart the Alerter

The final step is to restart the alerter. If the alerter was running as a Linux service, the service should now be restarted:

sudo systemctl restart panic_alerter

Otherwise, if you are not using Linux services perform this command in the project directory:

pipenv sync
pipenv run python run_alerter.py          # use sudo in linux if necessary
# If multiple versions of Python are installed, the python executable may be `python3.6`, `python3.7`, etc.

Run using Docker-Compose

Update and Run the UI Container

The first step is to obtain the updated UI docker image. This can either be done by re-building it manually or downloading it from Docker Hub.

Option 1: Building the Docker Image

Run the following command in the project directory to build the image:

docker-compose build ui

Option 2: Downloading the Pre-Built Docker Image from Docker Hub

The pre-built Docker image can simply be downloaded by running the following command:

docker pull simplyvc/panic_polkadot_ui:2.4.0

Run the UI docker image using this command:

docker-compose up -d ui
Update and Run the Alerter Container

Start by obtaining the updated alerter docker image. This can either be done by re-building it manually or by downloading it from Docker Hub

Option 1: Building The Docker Image

Run the following command to build the image:

docker-compose build alerter

Option 2: Downloading the Pre-Built Docker Image from Docker Hub

The pre-built Docker image can simply be downloaded by running the following command:

docker pull simplyvc/panic_polkadot:2.4.0

Now that the Docker image is on your machine, you can run it as follow:

docker-compose up -d alerter
