Development Notes

Run the following command to build arm64:

make BUILD_OS="linux" BUILD_ARCH="arm64"

Next, package the binary:

make BUILD_OS="linux" BUILD_ARCH="arm64" dist

After a successful release, upload packages to Github:

owner=$(cat .git/config  | egrep "^\s+url" | cut -d":" -f2 | cut -d"/" -f1)
repo=$(cat .git/config  | egrep "^\s+url" | cut -d":" -f2 | cut -d"/" -f2 | sed 's/.git$//')
tag="v$(< VERSION)"
github_api_token="PASTE_TOKEN_HERE"
filename="./dist/${repo}-$(< VERSION).linux-amd64.tar.gz"
upload-github-release-asset.sh github_api_token=${github_api_token} owner=${owner} repo=${repo} tag=${tag} filename=dist/ovs-exporter-$(< VERSION).linux-amd64.tar.gz
upload-github-release-asset.sh github_api_token=${github_api_token} owner=${owner} repo=${repo} tag=${tag} filename=dist/ovs-exporter-$(< VERSION).linux-arm64.tar.gz
