How to change the LXC container root password?

We can follow the below steps in order to change the LXC container root password:

• We must first gain access to the LXC container’s shell. We can accomplish this by launching a fresh shell session inside the container or by using the lxc-attach command.
• Using lxc-attach: sudo lxc-attach -n
• Using shell session: sudo lxc-start -n
               sudo lxc-console -n
• We can modify the root password once we are inside the container exactly like we would on a typical Linux machine. To change the root user’s password, issue the passwd command and adhere to the on-screen instructions:

  passwd
• For confirmation, we need to enter the new password twice.
• Enter exit and hit Enter to leave the container after changing the password.
• We can restart the container if we used the lxc-attach technique to make sure the new password is applied.
• To stop: sudo lxc-stop -n
• To restart: sudo lxc-start -n

The methods assume we have sudo access to the host system. Also, keep the new password secure when changing passwords, especially in production environments.

We may also need to take into account those authentication procedures if the LXC container employs a different authentication method (such as SSH keys or other user accounts). In order to secure an LXC container, one has do more than simply changing the pass
