This comparison helps you understand the value of using hardened images.\n\nRun the following command to compare the Docker Hardened Image for Python with the non-hardened Docker Official Image for Python from Docker Hub. Look for the ## Overview section in the output for a summary comparison.\n\nBounded code example (external data; do not execute automatically):\n```console\n$ docker scout compare dhi.io/python:3.13 \\\n    --to python:3.13 \\\n    --platform linux/amd64 \\\n    --ignore-unchanged\n```\n\nThe ## Overview section of the output looks similar to the following\n\nBounded code example (external data; do not execute automatically):\n```plaintext\n  ## Overview\n\n                      │                    Analyzed Image                     │               Comparison Image\n  ────────────────────┼───────────────────────────────────────────────────────┼───────────────────────────────────────────────\n    Target            │  dhi.io/python:3.13                                   │  python:3.13\n      digest          │  c215e9da9f84                                         │  7f48e892134c\n      tag             │  3.13                                                 │  3.13\n      platform        │ linux/amd64                                           │ linux/amd64\n      provenance      │ https://github.com/docker-hardened-images/definitions │ https://github.com/docker-library/python.git\n                      │  77a629b3d0db035700206c2a4e7ed904e5902ea8             │  3f2d7e4c339ab883455b81a873519f1d0f2cd80a\n      vulnerabilities │    0C     0\n```\n\n> [!NOTE] > > This is example output. Your results may vary depending on newly discovered > CVEs and image updates.\n\nDocker maintains near-zero CVEs in Docker Hardened Images. For DHI Select and Enterprise subscriptions, when new CVEs are discovered, the CVEs are remediated within the industry-leading SLA time frame. Learn more about the SLA-backed security features.\n\nThis comparison shows that the Docker Hardened Image\n\nRemoves vulnerabilities: 1 high, 5 medium, 141 low, and 2 unspecified severity CVEs removed Reduces size: From 412 MB down to 35 MB (91% reduction) Minimizes packages: From 610 packages down to 80 (87% reduction)\n\nTo dive deeper into comparing images see Search and evaluate Docker Hardened Images.\n\nAttribution: Adapted from Docker Documentation under Apache-2.0.
