docker-image-size-limit

Limit your docker image size with a simple CLI command. Perfect to be used inside your CI process.

Installation

pip install docker-image-size-limit

Usage

We support just a single command:

$ disl your-image-name:label 300MiB
your-image-name:label exceeds 300MiB limit by 14.4 MiB

Options

You can specify your image as:

• Image name: python
• Image name with tag: python:3.6.6-alpine

You can specify your size as:

• Raw number of bytes: 1024
• Human-readable megabytes: 30 MB or 30 MiB
• Human-readable gigabytes: 1 GB or 1 GiB
• Any other size supported by humanfriendly

Should I use it?

You can use this script instead:

LIMIT=1024
IMAGE='your-image-name:latest'

SIZE="$(docker image inspect "$IMAGE" --format='{{.Size}}')"
test "$SIZE" -gt "$LIMIT" && echo 'Limit exceeded'; false

But I prefer to reuse tools over custom bash scripts here and there.
