## jaildk - a FreeBSD jail development kit
|
||||||
FreeBSD jail development kit
|
|
||||||
|
This is the README for the FreeBSD jail utility `jaildk`. It can be
|
||||||
|
used to build, update, manage and run jails in a versioned environment.
|
||||||
|
|
||||||
|
Every jail consists of layers of directories mounted on top of each
|
||||||
|
other using nullfs mounts. Some of them can be shared among jails,
|
||||||
|
some are versioned.
|
||||||
|
|
||||||
|
## Installation
|
||||||
|
|
||||||
|
Execute the following command:
|
||||||
|
```
|
||||||
|
./jaildk setup <directory>
|
||||||
|
```
|
||||||
|
|
||||||
|
This will create the directory structure required for the tool install
|
||||||
|
the tool itself, create a template jail and build a base directory.
|
||||||
|
|
||||||
|
## Basic usage
|
||||||
|
|
||||||
|
Let's say you installed *jaildk* into `/jail` and you want to create a
|
||||||
|
new jail with the name 'myjail' and the ip address '172.16.1.1'.
|
||||||
|
|
||||||
|
The following steps need to be done:
|
||||||
|
|
||||||
|
### Configure /etc/jail.conf
|
||||||
|
|
||||||
|
Create the file `/etc/jail.conf` with the following innitial contents:
|
||||||
|
```
|
||||||
|
* {
|
||||||
|
exec.start = "/bin/sh /etc/rc";
|
||||||
|
exec.stop = "/bin/sh /etc/rc.shutdown";
|
||||||
|
allow.raw_sockets = "false";
|
||||||
|
sysvmsg = "new";
|
||||||
|
sysvsem = "new";
|
||||||
|
sysvshm = "new";
|
||||||
|
host.hostname = $name;
|
||||||
|
path = "/jail/run/$name";
|
||||||
|
exec.prestart = "/jail/bin/jaildk install $name all start";
|
||||||
|
exec.clean = "true";
|
||||||
|
}
|
||||||
|
|
||||||
|
myjail {
|
||||||
|
ip4.addr = "172.16.1.1";
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
Refer to [jail(8)](https://www.freebsd.org/cgi/man.cgi?query=jail&sektion=8) for more possible settings.
|
||||||
|
|
||||||
|
### Configure /etc/rc.conf
|
||||||
|
|
||||||
|
Next add the following lines to your `/etc/rc.conf`:
|
||||||
|
```
|
||||||
|
ifconfig_em0_alias0="inet 144.76.67.168/32"
|
||||||
|
jail_enable="YES"
|
||||||
|
```
|
||||||
|
|
||||||
|
You may need to replace the interface name `em0` with the one in use on your system.
|
||||||
|
|
||||||
|
|
||||||
|
### Create the jail
|
||||||
|
```
|
||||||
|
# jaildk create myjail
|
||||||
|
|
||||||
|
- cpdup -x /jail/log/.template-20201106 /jail/test/log/myjail-20201106
|
||||||
|
- cpdup -x /jail/home/.template/root-20201106 /jail/test/home/myjail/root-20201106
|
||||||
|
- cpdup -x /jail/etc/.template/etc-20201106 /jail/test/etc/myjail/etc-20201106
|
||||||
|
- cpdup -x /jail/etc/.template/local-etc-20201106 /jail/test/etc/myjail/local-etc-20201106
|
||||||
|
/jail/data/.template/www doesn't exist, ignored
|
||||||
|
/jail/data/.template/spool doesn't exist, ignored
|
||||||
|
- cp -pRp /jail/etc/.template/mount.conf /jail/test/etc/.template/ports.conf /jail/test/etc/.template/mtree.conf /jail/test/etc/myjail/
|
||||||
|
cp: /jail/etc/.template/ports.conf: No such file or directory
|
||||||
|
Creating /jail/etc/.template/jail.conf
|
||||||
|
Creating run and build dirs
|
||||||
|
- mkdir -p /jail/run/myjail
|
||||||
|
- mkdir -p /jail/build/myjail
|
||||||
|
DONE.
|
||||||
|
Consider adding the jail myjail to /etc/jail.conf!
|
||||||
|
|
||||||
|
To mount the build chroot of the new jail, execute:
|
||||||
|
jaildk build myjail
|
||||||
|
|
||||||
|
To login into the build chroot
|
||||||
|
jaildk blogin myjail
|
||||||
|
|
||||||
|
To mount the production chroot of the new jail, execute:
|
||||||
|
jaildk install myjail
|
||||||
|
|
||||||
|
To login into the build chroot
|
||||||
|
jaildk login myjail
|
||||||
|
|
||||||
|
To start the jail, execute:
|
||||||
|
jaildk start myjail
|
||||||
|
```
|
||||||
|
|
||||||
|
### Mount the build chroot of the jail
|
||||||
|
|
||||||
|
```
|
||||||
|
# jaildk build myjail
|
||||||
|
|
||||||
|
Installing jail myjail
|
||||||
|
mount - mount -t nullfs -o rw /jail/base/12.1-RELEASE-p10 /jail/build/myjail
|
||||||
|
mount - mdmfs -o rw,nosuid,async -s 128m -p 1777 md /jail/build/myjail/tmp
|
||||||
|
mount - mount -t devfs dev /jail/build/myjail/dev
|
||||||
|
mount - mount -t nullfs -o rw /jail/log/myjail-20201106 /jail/build/myjail/var/log
|
||||||
|
mount - mount -t nullfs -o rw /jail/appl/default-20201106 /jail/build/myjail/usr/local
|
||||||
|
mount - mount -t nullfs -o rw /jail/etc/myjail/etc-20201106 /jail/build/myjail/etc
|
||||||
|
mount - mount -t nullfs -o rw /jail/etc/myjail/local-etc-20201106 /jail/build/myjail/usr/local/etc
|
||||||
|
mount - mount -t nullfs -o rw /jail/home/myjail/root-20201106 /jail/build/myjail/root
|
||||||
|
```
|
||||||
|
|
||||||
|
### Chroot into the build dir and install software
|
||||||
|
|
||||||
|
```
|
||||||
|
jaildk blogin myjail
|
||||||
|
pkg install bash nginx curl ...
|
||||||
|
vi /usr/local/etc/rc.conf
|
||||||
|
vi /usr/local/etc/nginx/nginx.conf
|
||||||
|
```
|
||||||
|
|
||||||
|
Since the build chroot is writable you can install packages and
|
||||||
|
configure everything as needed.
|
||||||
|
|
||||||
|
### When done, install and start the jail
|
||||||
|
|
||||||
|
```
|
||||||
|
# jaildk install myjail
|
||||||
|
Installing jail myjail
|
||||||
|
mount - mount -t nullfs -o ro /jail/base/12.1-RELEASE-p10 /jail/run/myjail
|
||||||
|
mount - mdmfs -o rw,nosuid,async -s 128m -p 1777 md /jail/run/myjail/tmp
|
||||||
|
mount - mount -t devfs dev /jail/run/myjail/dev
|
||||||
|
mount - mount -t nullfs -o rw /jail/log/myjail-20201106 /jail/run/myjail/var/log
|
||||||
|
mount - mount -t nullfs -o ro /jail/appl/default-20201106 /jail/run/myjail/usr/local
|
||||||
|
mount - mount -t nullfs -o ro /jail/etc/myjail/etc-20201106 /jail/run/myjail/etc
|
||||||
|
mount - mount -t nullfs -o ro /jail/etc/myjail/local-etc-20201106 /jail/run/myjail/usr/local/etc
|
||||||
|
mount - mount -t nullfs -o rw /jail/home/myjail/root-20201106 /jail/run/myjail/root
|
||||||
|
|
||||||
|
# jaildk start myjail
|
||||||
|
Jail myjail start:
|
||||||
|
Starting jails: myjail.
|
||||||
|
|
||||||
|
# jaildk startus myjail
|
||||||
|
Jail scipown status:
|
||||||
|
JID IP Address Hostname Path
|
||||||
|
myjail 172.16.1.1 myjail /jail/run/myjail
|
||||||
|
Jail myjail rc status:
|
||||||
|
syslogd is running as pid 28180.
|
||||||
|
cron is running as pid 52130.
|
||||||
|
php_fpm is running as pid 45558.
|
||||||
|
nginx is running as pid 63975.
|
||||||
|
===> fcgiwrap profile: mediawiki
|
||||||
|
fcgiwrap is running as pid 37682.
|
||||||
|
```
|
||||||
|
|
||||||
|
### Login into the running jail for administration
|
||||||
|
```
|
||||||
|
# jaildk jlogin myjail
|
||||||
|
```
|
||||||
|
|
||||||
|
You can use this to login into a database or execute commands inside the jail.
|
||||||
|
|
||||||
|
|
||||||
|
### Updating a jail
|
||||||
|
|
||||||
|
The very first thing to do is to update the host system using `freebsd-update`.
|
||||||
|
|
||||||
|
Next create a new base version:
|
||||||
|
```
|
||||||
|
jaildk base `uname -r`
|
||||||
|
```
|
||||||
|
|
||||||
|
Now you can create clone of your jail with a new version:
|
||||||
|
```
|
||||||
|
jaildk clone myjail myjail 20201106 20210422
|
||||||
|
```
|
||||||
|
|
||||||
|
Mount the build chroot for the new version:
|
||||||
|
```
|
||||||
|
jaildk build myjail start `uname -r` 20210422
|
||||||
|
```
|
||||||
|
|
||||||
|
And finally chroot into the new jail and update it:
|
||||||
|
```
|
||||||
|
blogin myjail
|
||||||
|
pkg update
|
||||||
|
...
|
||||||
|
```
|
||||||
|
|
||||||
|
The last step is to remove the current running jail, change the version in `etc/myjail.conf`, install and start the new version.
|
||||||
|
|
||||||
|
If there's anything wrong you can always go back to the previous version using the above steps.
|
||||||
|
|
||||||
|
|
||||||
|
## Getting help
|
||||||
|
|
||||||
|
Although I'm happy to hear from jaildk users in private email,
|
||||||
|
that's the best way for me to forget to do something.
