How to update a the jail in a FreshPorts ingress node

Witness:

[19:32 r730-01 dvl ~/src/scripts] % file /jails/*-ingress01/jails/freshports/bin/sh
/jails/dev-ingress01/jails/freshports/bin/sh:   ELF 64-bit LSB pie executable, x86-64, version 1 (FreeBSD), dynamically linked, interpreter /libexec/ld-elf.so.1, for FreeBSD 13.2, FreeBSD-style, stripped

Instead of upgrading those jails, it might be easier to just redeploy them.

Do I already have a script for that?

Jails contain mkjail

I found this in command history: sudo mkjail create -j freshports2 -v 13.2-RELEASE

[dlangille]

That seems to have worked, despite an issue raised here: mkjail/mkjail#47

So far, the steps are:

• sudo mkjail create -j freshports2 -v 14.0-RELEASE
• Clone the ports tree into the new freshports jails: sudo git clone https://git.FreeBSD.org/ports.git /jails/freshports2/usr/ports
• cd /usr/local/libexec/freshports/Jail
• Copy scripts into the newly created jail:

[16:36 dev-ingress01 dan /usr/local/libexec/freshports/Jail] % sudo ./copy-scripts-into-jail.sh /jails/freshports2/                    
This entry is required in scripts/config.sh:
FRESHPORTS_JAIL_BASE_DIR="/jails/freshports2/"
This entry is required in /usr/local/etc/freshports/config.pm
$FreshPorts::Config::JailBaseDir = ${JAILBASE}

Except, that is not the required value, since we are going to swap jails.

• copy over vars.sh

[16:40 dev-ingress01 dan /usr/local/libexec/freshports/Jail] % diff -ruN /jails/freshports/vars.sh /jails/freshports2/vars.sh.sample 
[16:40 dev-ingress01 dan /usr/local/libexec/freshports/Jail] % sudo cp -ip /jails/freshports/vars.sh /jails/freshports2/

No diff, so just a straight copy.

• Check the time, minutes not close to a multiple of 3, so we can stop:

[16:58 dev-ingress01 dan ~/modules] % zfs list

[16:59 dev-ingress01 dan ~/modules] % 

Now the new jail is in place.

[16:59 dev-ingress01 dan ~/modules] % file /jails/*/bin/sh 
/jails/freshports.old/bin/sh: ELF 64-bit LSB pie executable, x86-64, version 1 (FreeBSD), dynamically linked, interpreter /libexec/ld-elf.so.1, for FreeBSD 13.2, FreeBSD-style, stripped

Then start the services back up:

[19:25 test-ingress01 dan /usr/local/libexec/freshports/Jail] % sudo service jail start
Starting jails: freshports.
[19:26 test-ingress01 dan /usr/local/libexec/freshports/Jail] % sudo service freshports start
Starting freshports.
