Provide a plain text file with the latest version of Camel K for easier automation of downloading via the tooling

[bfitzpat]

We have been working on setting up the VS Code extension to automatically download the Camel K CLI. For example, the Kubernetes extension provides this file: https://storage.googleapis.com/kubernetes-release/release/stable.txt. It simply provides the version number as a string (v1.16.1) that is then used in a generated URL - https://storage.googleapis.com/kubernetes-release/release/${version.result.trim()}/bin/${osString}/amd64/${binFile}

It would be great if we could do the same thing for the Camel K CLI - https://github.com/apache/camel-k/releases/download/${version}/camel-k-client-${version}-${platformString}-64bit.tar.gz

Maybe a simple text file in the github repo with "1.0.0-M2" in it?

You can eventually use github api like:

curl -s https://api.github.com/repos/apache/camel-k/releases/latest

Which gives you a json with information about the assets included in latest release.

Which gives you a json with information about the assets included in latest release.

That spits out a ton of detail in that json file, but we could certainly go that route. I was just looking for something simple. :)

I usually do something like that do download releases:

curl -s https://api.github.com/repos/${REPO_OWNER}/${REPO_NAME}/releases/latest \
    | jq --raw-output ".assets[] | select(.name | startswith(\"${BINARY_NAME}\")) \
    | .browser_download_url"

I don't know that I can rely on curl for Windows machines, which is a problem.

[lburgazzoli]

I meant that you can probably use a json path like the one I shown from your extension

That works. :)

async function getLatestCamelKVersion(): Promise<Errorable<string>> {
	const latestURL = 'https://api.github.com/repos/apache/camel-k/releases/latest';
	const downloadResult = await downloader.toTempFile(latestURL);
	if (failed(downloadResult)) {
		return { succeeded: false, error: [`Failed to establish kubectl stable version: ${downloadResult.error[0]}`] };
	}
	const rawtext = fs.readFileSync(downloadResult.result, 'utf-8');
	let latestJSON = JSON.parse(rawtext);
	let tagName = latestJSON.tag_name;
	if (tagName) {
		return { succeeded: true, result: tagName };		
	}
	return { succeeded: false, error: [`Failed to retrieve latest Apache Camel K version tag from : ${latestURL}`] };
}

Thanks Luca! Considering this one resolved. :)
