As wagoodman/dive does not come with an aarch64 image, I use this Dockerfile as one-file image builder on my RPi.

It has not thoroughly tested but it should work in most cases.

Usage

Docker Image

Build as usual, tagging it as the original image

docker build . -t wagoodman/dive:latest

then you can just use it with the official suggested run options:

docker run --rm -it \
    -v /var/run/docker.sock:/var/run/docker.sock \
    wagoodman/dive:latest <dive arguments...>

Binary

If your prefer to have a binary to install on your local system you use BuildKit and you will find the binary inside dist/ folder, building should consume about ~600MiB of disk space and it takes about ~130s on my RPi 4
NOTE: to build this you must have Docker 18.09 or higher

DOCKER_BUILDKIT=1 docker build --target=export-stage --output dist .

Cleanup

FYI, you can prune the builder cache doing

docker builder prune

Thanks, it almost worked for Raspberry Pi 4 (armv71).

I had to make two changes:

1. In the Dockerfile I changed $(uname -m) to armhf:

RUN wget -O- https://download.docker.com/linux/static/stable/armhf/docker-${DOCKER_CLI_VERSION}.tgz | \

2. I added the Docker version (obtained with docker -v) when building the image:

docker build . -t wagoodman/dive:latest --build-arg DOCKER_CLI_VERSION=20.10.12

This is great, thank you. It seems to work for aarch64 as well. Working with Nvidia Jetson docker files here.

I was hoping to use dive to inspect a very large (30GB) dev docker image since I don't have enough free space on the VM to do a docker save on it. Unfortunately it looks like dive also has to make a copy and i also ran out of disk trying to run dive... Oh well, time to expand the vm disk one more time.
