Exposing a directory on the host machine to an LXC container #blog

Exposing a directory on the host machine to an LXC container

  1. Log into the container and create an empty directory, this will be the mount point
  2. Log out and stop the container.
  3. Open to your container's config file
    • For regular LXC containers: /var/lib/lxc/mycontainer/config
    • For unprivileged LXC containers: $HOME/.local/share/lxc/mycontainer/config
  4. Add a new line above the lxc.mount directive, that follows the format below. Substitute proper paths as necessary:
    • lxc.mount.entry = /path/to/folder/on/host /path/to/mount/point none bind 0 0
  • Both of these paths are relative to the host machine.

Upgrading PostgreSQL from 9.4 to 9.6 on Debian Jessie

To use the most modern version of Postgres software we need to add postgresql repository. Edit /etc/apt/sources.list or create /etc/apt/sources.list.d/pgdg.list and add there a line: deb http://apt.postgresql.org/pub/repos/apt/ jessie-pgdg main Then import the repository signing key, and update the package lists:

wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
sudo apt-get update

Install a new version of PostgreSQL server.

Once the Debian upgrade finished, I used dpkg-query -l postgresql* to check which versions of postgres I have installed.
