Building Opennebula for Alpine Linux, hook_exe error

Hello!

I have a rather strange case - build Opennebula from sources for Alpine Linux 3.15.

At the end of the deployment, when I try to run oned, I get an error:

Wed Jun  8 23:18:46 2022 [Z0][ACL][I]: ACL Manager started.
Wed Jun  8 23:18:48 2022 [Z0][HKM][I]: Loading Hook Manager driver.
Wed Jun  8 23:18:48 2022 [Z0][DrM][I]: Loading driver: hook_exe
Wed Jun  8 23:18:48 2022 [Z0][DrM][I]: 	Driver loaded: hook_exe
Wed Jun  8 23:18:48 2022 [Z0][HKM][I]: 	Hook Manager loaded
Wed Jun  8 23:18:48 2022 [Z0][DrM][E]: Unable to start driver 'hook_exe': Driver initialization failed

Wed Jun  8 23:18:48 2022 [Z0][HKM][E]: Driver initialization failed

I found an issue in this community with a similar error - this one.
Unfortunately, the solution given in that issue doesn’t work for my case.

My deployment algorithm is the following:

  1. Create user:
adduser oneadmin
  1. Adding packages:
apk add libvncserver-dev libvncserver \
gnutls gnutls-dev libnsl libnsl-dev \
alpine-sdk linux-headers openssl-dev \
make bower npm ronn sqlite-dev \
mariadb-dev mariadb-server-utils mariadb-client \
ruby-dev libxml2 libxml2-dev libxml2 libxml2-dev \
xmlrpc-c xmlrpc-c-dev g++ scons bash
apk add ruby-nokogiri py3-ipaddress ruby-rexml \
ruby-xmlrpc ruby-bundler ruby-pg ruby-augeas augeas-dev \
libpg_query curl-dev libpq-dev
  1. Downloading sources:
git clone https://github.com/OpenNebula/one.git
cd one
  1. Making changes in src/svncterm_server/genfont.c file (due musl):
vim src/svncterm_server/genfont.c
#include <stdint.h>

typedef uint16_t u_int16_t;
  1. Compiling:
scons -j2 new_xmlrpc=yes
  1. Running some build scripts:
cd /root/one/share/man/
./build.sh

cd ~/one/src/fireedge/
./build.sh
  1. Installing Opennebula:
cd ~/one
./install.sh -u oneadmin -g oneadmin
  1. Intall Gems (!):
bundler install --gemfile /usr/share/one/Gemfile
  1. Additional actions:
apk add shadow

usermod -m -d /var/lib/one oneadmin

mkdir -p /var/lib/one/.one/
echo 'oneadmin:oneadm1n' >> /var/lib/one/.one/one_auth

chown oneadmin:oneadmin -R /var/log/one /var/lib/one /run/one /run/lock/one
  1. Aaaaaand starting Opennebula from oneadmin user:
fumoffu-test-node:~$ oned -f
Aborted
fumoffu-test-node:~$ 

Please tell me where I could make a mistake when deploying?
I think that something could screw up with gems.

Thanks in advance for your answers!

Hi @santic,

So if you try to start de hook driver manually, as explained in the issue you linked. Does it starts properly? or are you seeing any error?

Hi, @cgonzalez ,

After launching hook_manager (under oneadmin user) nothing happens, unfortunately:

I’ll try to understand deb-files.

I will dig further :slight_smile:

Installed czmq-dev and oned started.

Thanks everyone! I will try build the package :slight_smile:
