README for apt-dater-host
=========================
Setup hosts managed by apt-dater:
---------------------------------
You need a SSH server and `sudo` installed. Create a user (`the-user` in this
example) which will be used to install updates (using root is NOT recommended).
useradd the-user
Modify the sudoers rules, e.g. `/etc/sudoers` or `/etc/sudoers.d/apt-dater-host`:
Defaults env_reset,env_keep=MAINTAINER
the-user ALL=NOPASSWD: /usr/bin/apt-get, /usr/sbin/needrestart
For non apt-based distributions you need to replace
`/usr/bin/apt-get` with the equivalent, e.g. `/usr/bin/yum`.
You can verify the setup by calling
sudo -l -U the-user
Additional steps for a manual `apt-dater-host` installation:
------------------------------------------------------------
Put `apt-dater-host` on the managed host (folder must be present in `$PATH` of `the-user`).
Put `apt-dater-host.conf` to `$CFGFILE` (default is `/etc/apt-dater-host.conf`).
At your management server:
--------------------------
Create a user on your management server which perform updates on your
hosts.
Generate a SSH keypair:
ssh-keygen [..] -f ~/.ssh/apt-dater
Distribute the public key(s) e.g.:
ssh-copy-id -i ~/.ssh/apt-dater.pub the-user@managed-host
