Memcached: 4. GitHub Actions
This documentation is part of the GitHub Actions & GitLab CI guide. You can view the complete guide here: Launch a real Memcached service from your GitHub Actions or GitLab CI pipeline, run your tests against it, and automatically tear it down.
Welcome to the Stackhero documentation
Stackhero offers a fully managed Memcached cloud that simplifies application caching while ensuring security and high performance.
- Apply updates in just a few seconds with a single click.
- Benefit from consistent performance and enhanced security on a private, dedicated infrastructure.
Save time and focus on development. Stackhero's Memcached cloud hosting is up and running in around 5 minutes.
To get started, save the following as .github/workflows/ci.yml. From now on, every push and pull request will run tests against a real Memcached instance.
name: CI with Memcached
on: [push, pull_request]
jobs:
test:
runs-on: ubuntu-latest
env:
STACKHERO_TOKEN: ${{ secrets.STACKHERO_TOKEN }}
STACK_NAME: ci-memcached-${{ github.run_id }}-${{ github.run_attempt }}
INSTANCE: "1G" # Change this as needed (see step 3)
REGION: europe
steps:
- uses: actions/checkout@v4
- name: Install the Stackhero CLI and the client
run: |
curl -fsSL https://www.stackhero.io/install.sh | sh
apt-get update && apt-get install -y --no-install-recommends jq curl libmemcached-tools
- name: Create the Memcached service
run: |
set -euo pipefail
STACK_ID=$(stackhero --format=script stack-create --name="$STACK_NAME")
echo "STACK_ID=$STACK_ID" >> "$GITHUB_ENV"
SERVICE_ID=$(stackhero --format=script service-add \
--stack="$STACK_ID" \
--service-store="memcached" \
--instance="$INSTANCE" \
--region="$REGION")
echo "SERVICE_ID=$SERVICE_ID" >> "$GITHUB_ENV"
stackhero service-wait-for --service="$SERVICE_ID"
- name: Run tests against Memcached
run: |
set -euo pipefail
config=$(stackhero service-configuration-get --service="$SERVICE_ID" --format=json)
host=$(echo "$config" | jq -r '.configuration.domain')
user=$(echo "$config" | jq -r '.configuration.credentials.login')
password=$(echo "$config" | jq -r '.configuration.credentials.password')
# Authenticate with SASL and read a key (a miss still proves auth works).
memccat --servers="$host:11211" --binary --username="$user" --password="$password" stackhero-ci-probe 2>&1 | grep -vq "AUTHENTICATION"
echo "✅ Memcached is reachable from CI."
# You can run your own test suite here using the credentials above ...
- name: Tear down (always, even on failure)
if: always()
run: |
if [ -n "${SERVICE_ID:-}" ]; then
stackhero service-delete --service="$SERVICE_ID" --confirm
stackhero service-wait-for --service="$SERVICE_ID"
fi
if [ -n "${STACK_ID:-}" ]; then
stackhero stack-delete --stack="$STACK_ID" --confirm
fi
The teardown step uses if: always() to ensure it runs in all cases, guaranteeing your Memcached instance is deleted and you are not billed for unused resources.
