Selfhosted

A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

[HELP NEEDED] Unable to figure out directory permissions (infosec.pub)

Hi everyone,

This is my CONTAINERFILE for Bind9:

FROM debian

ENV LC_ALL C.UTF-8

# Update and upgrade system
RUN apt-get update -y && apt-get upgrade -y && apt-get dist-upgrade -y

# Install BIND 9 and sudo (for debugging if needed)
RUN apt-get install -y bind9 bind9-dnsutils bind9-libs bind9-utils sudo

# Configure permissions for BIND directories
RUN mkdir -p /var/cache/bind /var/lib/bind /var/log/bind
RUN chown -R bind:bind /var/cache/bind /var/lib/bind /var/log/bind
RUN chmod 664 /var/cache/bind /var/lib/bind /var/log/bind
RUN chmod -R 664 /var/cache/bind /var/lib/bind /var/log/bind

# Create and configure log files
RUN touch /var/log/bind/default.log /var/log/bind/update_debug.log /var/log/bind/security_info.log /var/log/bind/bind.log
RUN chown -R bind:bind /var/log/bind
RUN chmod 644 /var/log/bind/*.log

# Define volumes
VOLUME ["/etc/bind", "/var/cache/bind", "/var/lib/bind", "/var/log/bind"]

# Set the entrypoint to the named executable
ENTRYPOINT ["/usr/sbin/named"]

# Set the default command arguments for the named executable
CMD ["-g"]

I keep getting this error when I run it with podman:

26-Jul-2024 03:18:21.328 loading configuration from '/etc/bind/named.conf'
26-Jul-2024 03:18:21.328 directory '/var/cache/bind' is not writable
26-Jul-2024 03:18:21.332 /etc/bind/named.conf.options:2: parsing failed: permission denied

As you can see from the CONTAINERFILE, the bind user should be able to read and write to /var/cache/bind but for some reason it doesn't.

I have been at this for a while and I'm at my wits end. Your help is appreciated!

Thank you, I'll keep that in mind. I didn't actually mount volumes into the container yet, the problem was solved upon changing to chmod 755
