ziti-edge-tunnel Dockerfile for Debian
# this may still be useful for building arm 32bit images, e.g., assuming the binary was built in the default path,
# docker buildx build --platform linux/arm/v7 --file ./Dockerfile.debian --tag ziti-edge-tunnel:armv7 .
#
# run command "run-host" doesn't require elevated privileges, and "docker run --network container:myserverapp" would allow this container to host services targeting the loopback interface of "myserverapp"
# docker run --name ziti-host --detach --restart unless-stopped --network host --volume ziti-host:/ziti-edge-tunnel --env ZITI_ENROLL_TOKEN="$(< /tmp/jwt)" ziti-edge-tunnel:armv7
