# Seal My Container **Seal My Container** produces a sealed copy of your existing private container images. You feed Seal an image; Seal returns a sealed image that you push to your own registry. Vulnerable open-source packages, runtimes, and embedded artifacts inside the image are replaced with sealed versions; your own first-party application code is not touched. ## What it covers Inside the input container image: * OS-level packages, across the same Linux distributions as [Seal OS](/new-documentation/new-docs/product-family/seal-os.md): APK (Alpine), DEB (Debian, Ubuntu), and RPM (RHEL, and others). * Language runtimes installed in the image. * Open-source dependencies bundled as standalone artifacts (typically JAR files and Python wheels). Seal My Container does not modify your own first-party application code. ## How it is delivered Seal My Container runs as a Seal CLI command, typically from a centralized re-seal pipeline that processes a list of your container images. The output is a new container image you push to your registry under a name you choose. This pattern, container-to-container sealing, makes "fix the open-source software in every image we build" a single pipeline step instead of a per-image project. For pre-built open-source artifacts inside the image (JARs, Python wheels), Seal My Container uses [post-build artifact sealing](/new-documentation/new-docs/seal-approach/sealing-approaches.md). ## Related * [Setting up Seal My Container](https://github.com/seal-community/gitbook/blob/main/new-docs/setup-images-containers/seal-my-container/README.md): day-1 setup. * [Working with Seal My Container](https://github.com/seal-community/gitbook/blob/main/new-docs/using-platform/working-with-seal-my-container.md): the day-to-day workflow. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
