Running a IHP app build on github actions #1292
-
|
Hi, I would like to set up a CI build for my IHP project, any hints on how to do that? I found https://github.com/marketplace/actions/install-nix But not sure how that applies to a IHP project? |

Here's one github action file that builds an IHP app and then uses nix to copy it over to the production server. At the end the github action switches a symlink at name: Deployment
on:
push:
branches: [ master ]
jobs:
build:
runs-on: ubuntu-latest
steps:
- name: Checkout Code
uses: actions/checkout@v2
- name: Install nix and cachix
uses: cachix/[email protected]
with:
nix_path: nixpkgs=https://github.com/NixOS/nixpkgs/archive/51bcdc4cdaac48535dabf0ad4642a66774c609ed.tar.gz
- name: Cachix Init
uses: cachix/cachix-action@v10
with:
name: digitallyinduced
skipPush: true
- name: "Building"
run : nix-build -j auto --cores 0
- name: Install SSH Key
uses: shimataro/[email protected]
with:
key: ${{ secrets.KEY }}
known_hosts: ${{ secrets.KNOWN_HOSTS }}
name: id_rsa
config: |
Host production
HostName REPLACEME.eu-central-1.compute.amazonaws.com
User root
IdentityFile ~/.ssh/id_rsa
- name: "Copying Build"
run : nix --experimental-features nix-command copy --to ssh://production ./result
- name: "Migrate DB"
run: |
nix-shell --run migrate
env:
DATABASE_URL: ${{ secrets.DATABASE_URL }}
- name: "Enable Build"
run: ssh production "ln -sfT $(readlink -f ./result) /root/app"
- name: "Restart App"
run: ssh production "systemctl restart app worker"If you don't want to deploy the binary, remove all steps after For completeness here's also a nix file that fits the above github action: let
ihpEnv = {
PORT = "8000";
IHP_REQUEST_LOGGER_IP_ADDR_SOURCE = "FromHeader";
IHP_BASEURL = "https://someapp.digitallyinduced.com";
IHP_ENV = "Production";
DATABASE_URL = "REPLACEME";
IHP_SESSION_SECRET = "REPLACEME";
};

console = {

binaryCachePublicKeys = [ "digitallyinduced.cachix.org-1:y+wQvrnxQ+PdEsCt91rmvv39qRCYzEgGQaldK26hCKE=" ];
};

enable = true;

Thank you for sharing this. I'm trying to adapt this to my own workflow (deploying to a VPS) but am confused by this part: What does that do? |

A build step like this should do it: tests:
name: Run Tests
runs-on: ubuntu-latest
steps:
- uses: actions/[email protected]
- uses: cachix/install-nix-action@v12
with:
nix_path: nixpkgs=https://github.com/NixOS/nixpkgs/archive/c7f75838c360473805afcf5fb2fa65e678efd94b.tar.gz
- uses: cachix/cachix-action@v8
with:
name: digitallyinduced
skipPush: true
- run: |
cd $GITHUB_WORKSPACE
mkdir -p ~/.config/nixpkgs
echo "{ allowBroken = true; }" >> ~/.config/nixpkgs/config.nix
nix-shell --run "runghc $(make print-ghc-extensions) $(make print-ghc-options) Tests/Main.hs" |

Maybe you could provide an example ghc project where this is set up and point to it from the docs? I still can't get this to work |

Yes agree 👍
Yes, the testsuite will start it's own DB.
It looks like it's crashing because |

# Triggers the workflow on push or pull request events but only for the main branch
push:
branches: [ main ]
