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.

tar czfv NEW_NAME.tar.gz OLD_NAME --transform s/OLD_NAME/NEW_NAME/

Note: this only works with GNU Tar.

Example

we want to tar /opt/zlib/1.2.11 into zlib-1.2.11.tar.gz, and we want the top-level folder inside that tar.gz file to be zlib-1.2.11, not 1.2.11:

# How to use "acme.sh" to set up Lets Encrypt without root permissions
# See https://github.com/Neilpang/acme.sh for more

# This assumes that your website has a webroot at "/var/www/<domain>"
# I'll use the domain "EXAMPLE.com" as an example

# When this is done, there will be an "acme" user that handles issuing,
# updating, and installing certificates. This account will have the following
# (fairly minimal) permissions:
#   - Host files at http://EXAMPLE.com/.well-known/acme-challenge
