      From Wikipedia, the free encyclopedia\n
      \n
      Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
      \n
      Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
      \n
      ### Rules\n
      \n
      - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
      - No misinformation\n
      - No NSFW content\n
      - No hate speech, bigotry, etc\n

    Context\n
    -------\n
    \n
    I want to host public-facing applications on a server in my home, without compromising security. I realize containers might be one way to do this, and want to explore that route further.\n
    \n
    Requirements\n
    ------------\n
    \n
    I want to run applications within containers such that they\n
    \n
    - Must not be able to interfere with applications running on host\n
    - Must not be able to interfere with other containers or applications inside them\n
    - Must have no access or influence on other devices in the local network, or otherwise compromise the security of the network, but still accessible by devices via ssh.\n
    \n
    > Note: all of this within reason. I understand that sometimes there may be occasional vulnerabilities, like in kernel for example, that would eventually get fixed. Risks like this within reason I am willing to accept.\n
    \n
    What I found so far\n
    -------------------\n
    \n
    - **Running containers in rootless mode:** in other words, running the container daemon with an unprivileged host user\n
    - **Running applications in container under unprivileged users:** the container user under which the container is ran should be unprivileged\n
    - **Networking:** The container’s networking must be restricted. I am still not sure how to do this and shall explore it more, but would appreciate any resources.\n
    \n
    Alternative solution\n
    --------------------\n
    \n
    I have seen bubblewrap presented as an alternative, but it seems like it is not intended to be used directly in this manner, and information about using it for this is scarce.

      From Wikipedia, the free encyclopedia\n
      \n
      Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
      \n
      Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n
      \n
      ### Rules\n
      \n
      - Posts must be relevant to operating systems running the Linux kernel. GNU/Linux or otherwise.\n
      - No misinformation\n
      - No NSFW content\n
      - No hate speech, bigotry, etc\n

  +title: "How to secure (podman or docker) containers for public-facing hosting?"
  +url: null
  +body: """
    Context\n
    -------\n
    \n
    I want to host public-facing applications on a server in my home, without compromising security. I realize containers might be one way to do this, and want to explore that route further.\n
    \n
    Requirements\n
    ------------\n
    \n
    I want to run applications within containers such that they\n
    \n
    - Must not be able to interfere with applications running on host\n
    - Must not be able to interfere with other containers or applications inside them\n
    - Must have no access or influence on other devices in the local network, or otherwise compromise the security of the network, but still accessible by devices via ssh.\n
    \n
    > Note: all of this within reason. I understand that sometimes there may be occasional vulnerabilities, like in kernel for example, that would eventually get fixed. Risks like this within reason I am willing to accept.\n
    \n
    What I found so far\n
    -------------------\n
    \n
    - **Running containers in rootless mode:** in other words, running the container daemon with an unprivileged host user\n
    - **Running applications in container under unprivileged users:** the container user under which the container is ran should be unprivileged\n
    - **Networking:** The container’s networking must be restricted. I am still not sure how to do this and shall explore it more, but would appreciate any resources.\n
    \n
    Alternative solution\n
    --------------------\n
    \n
    I have seen bubblewrap presented as an alternative, but it seems like it is not intended to be used directly in this manner, and information about using it for this is scarce.
