▶️ Usage with vnc-template

  1. Reference this image in your Dockerfile:
FROM git.merith.xyz/gns3/vnc-template
  1. Add custom tools and configs in vnc-template:
RUN apk add firefox wireshark
COPY my-configs /etc/
  1. Auto start programs by adding your own entrypoint
COPY custom-entrypoint.sh /entrypoint.sh
RUN chmod +x /entrypoint.sh

⚠️ Do not add an ENTRYPOINT line in your Dockerfile.
The base image already defines the required entrypoint for proper operation in GNS3.

See vnc-template repository for full appliance creation guide.
