dab install package... howto?

[smilie]

Hi,

I was looking into the dab, but I am stuck on couple of issues here.

These are the steps that I have done.

First, I have downloaded following:
ftp://download.proxmox.com/sources/dab-pve-appliances_2009-01-19.tar.gz.
I have then unpacked it and cd to debian-5.0-minimal.
Then, I edited dab.conf, which is now:

Suite: lenny
CacheDir: ../cache
Source: http://ftp.nl.debian.org/debian SUITE main contrib non-free
Source: http://security.debian.org SUITE/updates main contrib non-free
#Mirror: http://ftp.debian.org/debian => ftp://mirror/debian
Architecture: i386
Name: debian-powerdns
Version: 1.0
Section: system
Maintainer: MAS Coders <info@mascoders.nl>
Infopage: http://www.mascoders.nl/openvz
Description: Debian 5.0 (PowerDNS)
 Minimal Debian 5.0 system with fully operational PowerDNS.

* don't mind incorrect Infopage, will be created when the time comes.

Then I did:
- dab init
- dab bootstrap --minimal
- dab task mysql --password=somepass --start
- dab install pdns-server

And then it hangs.
If I enter VE 9000, I can see the following:

ps -ef

[/COLOR]

And in the dpkg.log:

2009-02-21 10:24:52 startup archives install
2009-02-21 10:24:52 install pdns-server <none> 2.9.21.2-1

2009-02-21 10:24:52 status half-configured pdns-server 2.9.21.2-1

But proces "dab install pdns-server" remains hanging. Ctrl+C will kill it, but I don't think that is how it shoud be done

I have also tried with:
- dab bootstrap
without minimal, thinking that maybe some dependency was not met, but no luck.

This is command line where it hangs:

nononsense:~/downloads/dab-pve-appliances_2009-01-19/debian-5.0-minimal# dab install pdns-server
install: pdns-server




interrupted by signal

My second question is:
I tried installing only mysql (dab task mysql). This goes fine. Once installed, I have done "dab exec ps -ef" and I can see MySQL proccess up & running.

After that I have done:

- dab finalize
- dab dist-clean
- make

This creates a new ostemplate (.tar.gz). I have then moved this template to the template directory of /vz/. I went to the web interface and created new OpenVZ VPS with newly created template. Creation went oke, and I started new VPS.

But, then if I enter that VPS, I can not find MySQL nowhere. No proccess, no init script, no binaries, no nothing regarding mysql

What am I doing wrong here? I thought that purpose of dab was to pre-create .tar.gz, so that when you create VPS with that ostemplate, that you will have all packages installed?

See above, in dab list - mysql-server mysql-client and mysql-common are present, butI can not find / use them once I install that template :S

=====

Last question for now.
I have provided info in dab.conf (description). However, in the web interface, in the Appliance templates, it says Description: --unknown--

Thanx

Cheers,
Aleks

One more thing, in man pages, you have wrong url in:

DESCRIPTION
dab is a script to automate the creation of OpenVZ appliances. It is
basically a rewrite of debootstrap in perl, but uses OpenVZ instead of
chroot and generates OpenVZ templates. Another difference is that it
supports multi-stage building of templates. That way you can execute
arbitrary scripts between to accomplish what you want.

Furthermore some common tasks are fully automated, like setting up a
database server (mysql or postgres).

To accomplish minimal template creation time, packages are cached to a
local directory, so you do not need a local debian mirror (although
this would speed up the first run).

See http://pve.proxmox.com/Debian_Appliance_Builder for examples.

This script need to be run as root, so it is not recommended to start
it on a production machine with running container. Proxmox VE
(http://pve.proxmox.com) is the preferred environment, because it is
able to log the console output when a container starts. You wont be
able to detect errors during container startup when running on standard
OpenVZ. So many people run Proxmox VE inside a KVM or VMWare 64bit vir‐
tual machine to build appliances.

All generated templates includes an appliance description file. Those
can be used to build appliance repositories."

It should be:
http://pve.proxmox.com/wiki/Debian_Appliance_Builder

Aleks

I think I must correct myself for the second issue (no mysql in template).
Just tested a few more times. Seems that executing "make" deletes all installed applications?! Is this normal behavior?

If I use template after "dab finalize" then it has all installed applications in it.
What is then purpose of make?!

Maybe an idea to re-write that page, may be confusing for less experienced people as myself

Other two issues remain valid / active.

Aleks

But proces "dab install pdns-server" remains hanging. Ctrl+C will kill it, but I don't think that is how it shoud be done

Isnt there a hint in 'logfile' ?

This is command line where it hangs:

nononsense:~/downloads/dab-pve-appliances_2009-01-19/debian-5.0-minimal# dab install pdns-server
install: pdns-server

This simply install all packages with 'dpkg' inside the container. Seems that the pdns-server.postinst script is doing something strange?

After that I have done:

- dab finalize

No you have the final template.

- dab dist-clean

This removes anything you have done so far!

- make

This start the command in Makefile. You should make yourself familiar with Makefiles if you use make.

But, then if I enter that VPS, I can not find MySQL nowhere. No proccess, no init script, no binaries, no nothing regarding mysql

because 'make' created a standard debian template with 'Makefile'.

Last question for now.
I have provided info in dab.conf (description). However, in the web interface, in the Appliance templates, it says Description: --unknown--

Thats simply not implemented - we are working on that.

Please read the make domumentation first!

Dietmar,

Thanks for replies.
I guessed that dab clean would remove everything. I would still suggest to change wiki page, as it now first suggests to do dab clean, and then make. This, as you have said (and I have experienced) removes all made changes in the installation Just add somewhere that after dab finalize, a .tar.gz is ready for use.

As I read it, MakeFile only simplifies things? I am more of a control freak, so I will keep doing things manually. Good to know though.

I shall try to install pdns once again a bit later and post logfile.

Regarding --unknown-- in web interface, how come that appliances downloaded from your website do have this option? Any idea when will this functionality be available?

Cheers,
Aleks

The website is correct - maybe you should just read it more carefully. Or what paragraph do you refer to?

This, as you have said (and I have experienced) removes all made changes in the installation Just add somewhere that after dab finalize, a .tar.gz is ready for use.

Thats already there.

Regarding --unknown-- in web interface, how come that appliances downloaded from your website do have this option? Any idea when will this functionality be available?

We are working as fast as possible. The plan is to have that fully functional in June.

Thanks for all usefull info Dietmar!

deb and dab

I had to manually install the deb package because apt-get install dab would not resolve and load so I did the wget and had to understand/run the basic following install commands:

Code:
dpkg -i dab_1.1-1_all.deb
apt-get -f install


FYI, now i am good to go!
