What is the most accessible way to get ulid in Docker image?

[gajus]

Installing the entire Node.js as a dependency is ... inefficient to say the least.

None of the Python libraries seem to provide CLI interface.

Is there a recommended program?

I need ulid ID as part of a build process.

[gajus]

A fairly reasonable one-liner:

apt-get update -y && apt-get install -y python-pip && pip install python-ulid && python -c 'from ulid import ULID; print ULID.new().str'

[alizain]

You might have better luck with some one of the two go implementations. They should be available as static binaries with 0 dependencies!

[gajus]

Well, what would be the one-liner for those?

[alizain]

I have no idea, you'll have to check with those specific projects.

FWIW, if you do decide to install node as a dependency, this implementation also has a command line interface, so your one-liner would be:

apt-get install node && npm install -g ulid && ulid

FYI For whatever reason ulid install failed.

$ apk add --update nodejs nodejs-npm && npm install -g ulid && export RELEASE_ID=$(ulid)

Oh dear, what a silly bug. I'll have it cleared in a moment.

[alizain]

Just released v2.2.1, let me know if it solves your issues!

[alizain]

A quick note - running ulid on the command line will not output a newline character.

It does.
