dnsimple-terraform-ip-fixer

Usage

This container consumes the following environment variables:

Name	Description
TFC_TOKEN	A user token from the Terraform Cloud account
TFC_WORKSPACE_ID	The ID of the workspace in the Terraform Cloud organization in which the IP is set

Building

This Docker image is built for ARM 32 v7 architecture. To build the image on a machine of a different architecture, we need to use the experimental buildx feature:

# from the root of this repository:

docker buildx build --platform linux/arm/v7 -t docker-registry.tlake.io/tlake/dnsimple-terraform-ip-fixer . --push

Make sure that we've done docker login docker-registry.tlake.io.

Enabling Multi-Arch Builds

In the event that these resources go away, here's an attempt to copy down the relevant info:

You need to enable execution of different multi-architecture containers by QEMU and binfmt_misc.

In recent distro this can be simply done by running:

apt-get install qemu-user-static

If this doesn't work for you, you can execute :

docker run --rm --privileged multiarch/qemu-user-static --reset --persistent yes --credential yes

Note that this may reconfigure any existing binfmt_misc setup that you have. See https://github.com/multiarch/qemu-user-static for more detail.
