Ubuntu1804VagrantBoxCreate

TurnToJPG -->

For creating Ubuntu 18.04 vagrant box, follow the following steps:

Change grub configuration for changing to ethx naming rules:

# vim /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quite"
GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"
# grub-mkconfig -o /boot/grub/grub.cfg

Change the netplan rules:

# vim /etc/netplan/01-netcfg.yaml 
# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:
  version: 2
  ethernets:
    eth0:
      dhcp4: yes
      dhcp-identifier: mac

Now reboot your machine, continue for later commands.

Create vagrant user and set the password, etc.

# useradd -m vagrant
# passwd vagrant
# visudo
vagrant ALL=(ALL)	NOPASSWD:ALL
Defaults:vagrant	!requiretty
# mkdir -p /home/vagrant/.ssh
# chmod 0700 /home/vagrant/.ssh/
# wget --no-check-certificate     https://raw.github.com/mitchellh/vagrant/master/keys/vagrant.pub     -O /home/vagrant/.ssh/authorized_keys
# cat /home/vagrant/.ssh/authorized_keys 
# chmod 0600 /home/vagrant/.ssh/authorized_keys
# chown -R vagrant /home/vagrant/.ssh
# cp /home/test/.bashrc /home/vagrant/.bashrc 
# cp /home/test/.bash_logout /home/vagrant/.bash_logout
# cp /home/test/.profile /home/vagrant/.profile
# vim /home/vagrant/.profile 
add
[ -z "$BASH_VERSION" ] && exec /bin/bash -l
# chsh -s /bin/bash vagrant

Finally change the sshd configuration:

# vim /etc/ssh/sshd_config 
AuthorizedKeysFile .ssh/authorized_keys

Now you could halt you machine.

Package to a box via:

$ vagrant package --base xxxx

Using the package.box , then you could mutate to libvirt or do some other things.

For kubespray offline

Install ansible via:

# apt-get update && apt-get install -y python-pip && pip install ansible

Or use old ansible(from repository):

# apt-get update -y && apt-get install -y ansible

Better you use the ppa repository for installing ansible:

# apt-add-repository ppa:ansible/ansible
# apt-get install ansible

Generate the ssh key and use ssh-copy-id for copying the key for passwordless login.

Download kubespray source files:

# wget  https://github.com/kubernetes-sigs/kubespray/archive/v2.8.1.tar.gz
# tar xzvf v2.8.1.tar.gz
# vim inventory/sample/host.ini
[all]
node ansible_host=192.168.33.109 ip=192.168.33.109 etcd_member_name=etcd1

[kube-master]
node

[etcd]
node

[kube-node]
node

[k8s-cluster:children]
kube-master
kube-node
# vim inventory/sample/group_vars/k8s-cluster/k8s-cluster.yml
kube_version: v1.12.4

Deploy online for:

# ansible-playbook -i inventory/sample/hosts.ini cluster.yml

Now you could get all of the deb packages and docker images.

1804 debs preparation

Generate 1804debs.tar.xz files.
