v2.0.0

• JSON lines: TraceTrout now outputs line-separated JSON objects.

v1.4.0

• Added autocert: Integrated Let's Encrypt support activated and controlled by the following environment variables:
  • HTTPS_AUTOCERT_ENABLED: Set to true to enable autocert.
  • HTTPS_AUTOCERT_HOSTS: A comma-separated list of hostnames that autocert applies to. If not defined then applies to every host.
  • HTTPS_AUTOCERT_DIR_CACHE: A directory where Let's Encrypt data is cached. If not defined then the data is cached in memory.
• INFO_URI_TEMPLATE: RFC 6570-style URI template for fetching extra information to each trace hop.

Example docker-compose.yml:

version: "3"

services:
  tracetrout:
    image: hownetworks/tracetrout
    volumes:
      - autocert-cache:/autocert-cache
    environment:
      HOP_OFFSET: "1"
      INFO_URI_TEMPLATE: http://whereabouts:8080/ip/{ip}
      HTTPS_ENABLED: "true"
      HTTPS_AUTOCERT_ENABLED: "true"
      HTTPS_AUTOCERT_HOSTS: tracetrout4.example.com,tracetrout6.example.com
      HTTPS_AUTOCERT_DIR_CACHE: /autocert-cache
    ports:
      - "443:8080"
    cap_add:
      - NET_ADMIN

  whereabouts:
    image: hownetworks/whereabouts

volumes:
  autocert-cache: {}

v1.3.4

• Migrate the code to Go 1.11's module system.
• Build the container with Go 1.11 and Alpine 3.8.

v1.3.3

• Limit the trace responses to the root path /
• The Docker image entrypoint passes e.g. SIGTERM signals to the tracetrout binary

v1.3.2

• Build a Docker image with ipv6 support separately, available as hownetworks/tracetrout:ipv6

v1.3.1

• Add ip6tables setup to the Docker entrypoint

TraceTrout over IPv6

• Add IPv6 support (no proper ip6tables setup yet in the Docker image)
• Use alpine:3.7 as the base Docker image
• Modify the Docker image's entrypoint to allow multiple instances running e.g. on the same Kubernetes pod

TraceTrout over HTTPS

Set HTTPS_ENABLED=true to enable HTTPS. This also requires setting HTTPS_CERT_FILE to point to your HTTPS certificate file and HTTPS_KEY_FILE to point to the key file for the certificate.

v1.1.0

Add request logging.

v1.0.0

Add circle.yml
