perf-containers

perf-containers provides Docker images for JMeter, k6, and Gatling with all protocol plugins and drivers pre-installed. Run performance tests anywhere Docker runs without managing tool installations.

Tier	Price
Private Registry	£300/year

All images are hosted on registry.martkos-it.co.uk. A license key is required to pull — purchase at martkos-it.co.uk/store/perf-containers.

Getting Registry Access

After purchasing, Lemon Squeezy emails your license key. Use the download page to generate a registry token, then authenticate:

TOKEN=$(curl -s https://updates.martkos-it.co.uk/api/v1/registry-token \
  -H "X-License-Key: your-license-key" \
  -H "X-Product: perf-containers" | jq -r '.token')

echo "${TOKEN}" | docker login registry.martkos-it.co.uk \
  --username your@email.com \
  --password-stdin

Tokens are valid for 5 minutes. Regenerate before each docker pull or CI/CD run.

Image Tags

Tags follow semantic versioning:

registry.martkos-it.co.uk/perf-jmeter:latest   # latest stable
registry.martkos-it.co.uk/perf-jmeter:1.0.0    # exact version (immutable)

Architecture

All images are multi-arch: linux/amd64 and linux/arm64. Docker selects the correct variant automatically on pull.
