docker-repack - Speed up Docker image pulls
This tool repacks a Docker image into a smaller, more efficient version that makes it significantly faster to pull. It does this by using a few different techniques such as removing redundant data and improving compression ratios. Some examples of improvements:
| Image | Before | After | Reduction |
|---|---|---|---|
| google/deepsomatic | 16.4GB, 2 minutes 14 seconds | 4.8GB, 16 seconds | 3.4x smaller, 8.2x faster |
| google/deepvariant | 12.7GB, 1 minute, 2 seconds | 3GB, 10 seconds | 6.3x faster, 4.2x smaller |
| google/cloud-sdk | 1.1GB, 5 seconds | 187MB, 1 second | 3.8x faster, 6.1x smaller |
| mathworks/matlab | 2GB, 5 seconds | 230.7MB, 1 second | 6.5x faster, 9x smaller |
| tensorflow/tensorflow | 3.5GB, 11 seconds | 2GB, 3 seconds | 3.3x faster, 1.8x smaller |
See the benchmarks page for a full comparison of pulling times across many different images.
