Docker

Run Speedscale components via Docker Compose.

Prerequisites​

  1. Speedctl is installed
  2. Docker Desktop is installed

Capturing Traffic​

Create Docker Compose manifests by running speedctl install, and following the Docker flow that allows you to capture traffic. This will create working manifests with sane defaults. The created manifest file will be listed after the command completes.

Bring up the containers using docker compose --file <speedscale-manifest-file> up -d which will start the containers described in the compose file. These containers will aid in capturing traffic and sending it to the Speedscale cloud.

Now you have to configure your application to use the socks proxy running on *:4140 on your server, and configure it to trust the local certificates.

You can now run requests against your service through localhost:4143 instead of the normal port as our goproxy is acting as the entry point for the app now.

Analyze Traffic​

Traffic

You should be able to see traffic in the Speedscale UI after a few minutes and now you can using this traffic to create a snapshot.

Replaying Traffic​

Replaying traffic starts by creating manifests similar to the capture step above. Run speedctl install and choose the Docker flow that allows you to replay recorded traffic. When prompted, enter the ID of the snapshot you created.

This will generate a report which you can find on the reports page.

note

The speedctl install command is just a helper and environment variables like SNAPSHOT_ID and TEST_CONFIG_ID can be modified in the manifest file without regenerating it every time.
