An Introduction to bind mount in LXC

Did you know that the bind mounting technique in LXC is used to mount directories or files from the host system into the container?

This is a handy feature when we want to offer access to specific files or directories on the host system to the container. Additionally, it makes it easier to share data between the host system and the container.

According to our experts, we can easily carry out a bind mount in an LXC container with these steps:

1. To begin with, we have to create a directory on the host system that we want to mount into the container.
2. Then, we must edit the container configuration file in order to add a “mount” entry. This entry mentions the source as well as destination directories for the bind mount.

   For example,

   lxc.mount.entry = /mnt/newdir /var/lib/lxc/mycontainer/rootfs/mnt/newdir none bind 0 0

   Here, /mnt/newdir is the source directory on the host system, and /var/lib/lxc/mycontainer/rootfs/mnt/newdir is the destination directory in the container.
3. Next, restart the LXC container for the changes to take effect.

   sudo lxc restart containername

Once we are done with the above steps, the directory “/mnt/newdir” on the host system will be mounted as “/mnt/newdir” inside the container. All changes made to the directory in the host system will be reflected on the container and vice versa.

Our experts would like to point out that we have to be careful while using bind mounts since they can expose sensitive data from the host system to the container. This is why we have to ensure that the mounted directories are secure and only accessible to authorized users.
