Body

I am retrieving environments dynamically using strategy and matrix. I want to do sequence deployment not parallel. I am trying to add needs but needs doesn't work dynamically. Please help to do sequence deployment. For example, if prod deployment is happening it should wait for lower environment. Once lower environment deploys then only Prod deploy

name: Env Read

on:
workflow_dispatch:

jobs:
get-environments:
runs-on: ubuntu-latest
outputs:
names: ${{ steps.set_env.outputs.names }}
steps:
- name: Get Environments
uses: octokit/[email protected]
id: get_env
with:
route: GET /repos/${{ github.repository }}/environments?per_page=100 # If we ever have >100 deployments, we'll need to paginate
env:
GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
- name: Set output
id: set_env
# run: echo "names=$(echo $NAMES | jq -c '[.[] | select(startswith("[${{ github.ref_name }}]"))]' -j)" >> $GITHUB_OUTPUT
env:
NAMES: ${{ toJson(fromJson(steps.get_env.outputs.data).environments.*.name) }}
run: |
# use heredoc with random delimiter for multiline JSON
delimiter="$(tr -dc A-Za-z0-9 </dev/urandom | head -c 20)"
echo "names<<$delimiter
$NAMES
$delimiter" >> "$GITHUB_OUTPUT"

environment:
name: ${{ matrix.environment }}
