ARM64 image ?

[ErfanDL]

Hi, how can I build ARM64 image for docker ?

[thehilll]

This is possible with some slight modifications. I could provide a pull request, but it does break some functionality noted below).

I am running the current version with postgres on ARM, but I don't know how to get mongo to work if you want to use that. To use it with postgres:

• Clone the repo

git clone https://github.com/alerta/docker-alerta.git
cd docker-alerta

• As far as I can tell the version of mongodb-org-shell used (4.2) does not have a pre-built binary for ARM64. I have found instructions to build it yourself, but that's a larger change to the Dockerfile. It also might be possible to use a newer version which I believe does have a pre-built ARM version, but I don't know.
• Because I'm not using mongo I just commented out the lines in the Dockerfile and in docker-entrypoint.sh that depend on it:

• You can then build an image by specifying the platform to be ARM:

docker build \
  --platform=linux/arm64/v8 \
  --build-arg VCS_REF=(git rev-parse --short HEAD) \
  --build-arg BUILD_DATE=(date -u +"%Y-%m-%dT%H:%M:%SZ") \
  --build-arg VERSION=(cat VERSION) \
  -t alerta-web:20230906 .

• You will now have this image on your machine, but you need to create a docker-compose.override.yml to use it rather than the one specified in docker-compose.yml:

version: '2.1'
services:
  web:
    image: alerta-web:20230906

• At this point you can proceed as the README says:

docker-compose up -d

# and to see what is happening:
docker logs -f alerta_web_1
