IC Deploy Action

Introduction

Fleek's IC deploy action wraps commands from the dfx command line tool, which deploys canister to the Internet Computer.

The Github Action will trigger a new deployment to the Internet Computer when commits are pushed.

Example Usage

Create a .github/workflows/deploy.yml workflow file in your repository with the following configuration:

on: [push]

jobs:
  test-deploy:
    runs-on: ubuntu-latest
    name: A job to deploy canisters to the IC
    steps:
      - uses: actions/checkout@v2
      - name: Install dependencies
        run: npm install
      - name: Deploy canisters
        id: deploy
        uses: fleekhq/ic-deploy-action@master
        with:
          identity: ${{ secrets.DFX_IDENTITY }}
          wallets: ${{ secrets.DFX_WALLETS }}
      - name: Show success message
        run: echo success!

Initial Setup

Before including the Github Action to your CI/CD pipeline, you need a project configured and deployed to the IC.

If it's not already done, create a new project with the dfx CLI.

dfx new hello-world

Then, you can make an initial deployment to the IC after having installed dependencies with npm install if necessary.

dfx deploy --network=ic

The canisters are now deployed. At this point, a canister_ids.json file will have been created in your repository. It's important to push this file to github, because it identifies your Canister on the IC.

Furthermore, these canisters have been deployed with a particular identity, which you by default is called default. We will have to export the private key associated with that identity through a Github secret.

Github Secrets

As seen in the code snippets in the previous section, the Github Action necessitates the addition of two secrets in order to make additional deployments through the same identity.

DFX_IDENTITY

We have to export the content of your default identity and modify it so that it fits in a single line.

First, locate your identity. For the default identity on Linux, it can be found in the following location ~/.config/dfx/identity/default/identity.pem.

Run the command below and copy the output to the DFX_IDENTITY Github Secret. The command below can be modified if the path to the identity.pem file differs.

awk 'NF {sub(/\r/, ""); printf "%s\\r\\n",$0;}' ~/.config/dfx/identity/default/identity.pem

DFX_WALLETS

Copy the contents of the wallets.json file that in the same directory as the identity.pem file and paste it to the DFX_WALLETS Github secret. The content of the file can be retrieved by the code below.

cat ~/.config/dfx/identity/default/wallets.json

Note that this file will not be present if you have not initially deployed the canisters.

Optional inputs

Network

By default, the action will deploy with the command dfx deploy --network=ic, but the value of ic can be overriden through the network input.

on: [push]

jobs:
  test-deploy:
    runs-on: ubuntu-latest
    name: A job to deploy canisters to the IC
    steps:
      - uses: actions/checkout@v2
      - name: Install dependencies
        run: npm install
      - name: Deploy canisters
        id: deploy
        uses: fleekhq/ic-deploy-action@master
        with:
          identity: ${{ secrets.DFX_IDENTITY }}
          wallets: ${{ secrets.DFX_WALLETS }}
          network: alpha
      - name: Show success message
        run: echo success!

dfx_params

The parameters of the dfx call can be customized with the dfx_params input. This input will simply append the content of the input to the dfx command. For example, in order to run, dfx --no-wallet instead of the default dfx, input --no-wallet to this input.

on: [push]

jobs:
  test-deploy:
    runs-on: ubuntu-latest
    name: A job to deploy canisters to the IC
    steps:
      - uses: actions/checkout@v2
      - name: Install dependencies
        run: npm install
      - name: Deploy canisters
        id: deploy
        uses: fleekhq/ic-deploy-action@master
        with:
          identity: ${{ secrets.DFX_IDENTITY }}
          wallets: ${{ secrets.DFX_WALLETS }}
          dfx_params: --no-wallet
      - name: Show success message
        run: echo success!

Contributing

There are a lot of variations of Canister deployments possible, such as not using the default identity and wallet, different working directories, deployments that flushes the memory in the canisters and some that don't, etc...

Any contributions that offer more flexibility and options are very valuable!
