CI/CD

Integrate proxymock into your CI/CD workflow to enable high-velocity deployment with confidence.

Run proxymock after your build and unit tests, but before deploying to production.

CI Pipeline

Adding anything to your CI/CD pipeline generally involves the same 3 steps:

Adding a step to your pipeline (see #1. The Pipeline)
Executing the right script to perform a desired action (see #2. The Script)
Authentication (see #3. The API Key)

Prerequisites

In order to integrate proxymock into your CI/CD you will need:

Access to modify your CI/CD pipeline
Your proxymock API key
A paid proxymock account (see proxymock.io for pricing details)
Pre-recorded traffic files (see recording to record from your app)

1. The Pipeline

These pipeline examples contain the minimal configuration needed to run proxymock with your application.

Examples build a Go binary using go build using the golang container image. Your image can be anything you choose as long as proxymock has access to your application.

2. The Script

Let's fill in the proxymock.sh script shown above. Be sure to customize the user settings at the top of the script.

warning

The script expects the SPEEDSCALE_API_KEY environment variable to be set (securely) for authentication. See The API Key.

#!/usr/bin/env sh

# set the port your application will listen on, where traffic will be replayed
APP_PORT=8080
# set the command to run your application.  ensure this command has all of the
# correct flags and that the environment has all of the configuration needed to
# run your application properly
APP_COMMAND="./my-example-app --log-level debug" # CHANGE ME!

# the path to pre-recorded proxymock traffic
PROXYMOCK_IN_DIR="proxymock"
# optionally, run mock server
RUN_MOCK_SERVER=true

3. The API Key

proxymock requires a valid API key to run. Your API key is created when you first run proxymock init and is stored in a config file, at $HOME/.speedscale/config.yaml by default.

To make it easy, once registered you can get your API key directly with some command line magic:

SPEEDSCALE_CONFIG_FILE=$(proxymock version | grep 'Config File' | awk '{print $3}')
SPEEDSCALE_API_KEY=$(cat $SPEEDSCALE_CONFIG_FILE | grep apikey | awk '{print $2}')
echo $SPEEDSCALE_API_KEY

info

If this does not produce an API key make sure you are registered first with proxymock init.

Make SPEEDSCALE_API_KEY available to your pipeline as an environment variable so proxymock can be initialized when the pipeline runs.
