AIM

For upgrading the offline installation of kubespray from 1604 to 1804.

Ansible

Get the ansible debs via following command:

# apt-get update
# apt-get install  install software-properties-common
# apt-add-repository ppa:ansible/ansible
# apt-get install ansible
# mkdir /root/debs && cd /var/cache
# find . | grep deb$ | xargs -I % cp % /root/debs

You should change the vagrant box’s configuration:

# vim /etc/netplan/01-netcfg.yaml
    eth0:
      dhcp4: yes
+      dhcp-identifier: mac

The vagrant file(shell provision) should be like following:

rm -f /etc/resolv.conf
ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf
echo '      nameservers:'>>/etc/netplan/50-vagrant.yaml
echo '        addresses: [10.148.129.101]'>>/etc/netplan/50-vagrant.yaml
netplan apply eth1

task Changes

Judge for OS version changes:

# vim roles/kube-deploy/tasks/main.yml
- name: Set ubuntu_version
  set_fact:
    ubuntu_version: >-
      {%- if 'bionic' in os_release.stdout -%}
      bionic
      {%- elif 'xenial' in os_release.stdout -%}
      xenial
      {%- endif -%}

# vim roles/kube-deploy/deploy-ubuntu.yml
  - name: "upload debs.tar.xz files to kube-deploy(Xenial)"
    copy:
      src: files/1604debs.tar.xz
      dest: /usr/local/
      owner: root
      group: root
      mode: 0777
    when: ubuntu_version == "xenial"

  - name: "Install ansible and python-netaddr(Xenial)"
    raw: cd /usr/local/ && tar xJvf 1604debs.tar.xz -C /usr/local/ && echo "deb [trusted=yes] file:///usr/local/static ./">/etc/apt/sources.list && apt-get u
pdate -y && apt-get install -y ansible python-netaddr && rm -f /usr/local/debs.tar.xz
    when: ubuntu_version == "xenial"

  - name: "upload debs.tar.xz files to kube-deploy(Bionic)"
    copy:
      src: files/1804debs.tar.xz
      dest: /usr/local/
      owner: root
      group: root
      mode: 0777
    when: ubuntu_version == "bionic"

  - name: "Install ansible and python-netaddr(Bionic)"
    raw: cd /usr/local/ && tar xJvf 1804debs.tar.xz -C /usr/local/ && echo "deb [trusted=yes] file:///usr/local/static ./">/etc/apt/sources.list && apt-get u
pdate -y && apt-get install -y ansible python-netaddr && rm -f /usr/local/debs.tar.xz
    when: ubuntu_version == "bionic"

Also you have to change the Vagrantfiles:

File.open('./dns.sh' ,'w') do |f|
  f.write "#!/bin/bash\n"
  f.write "sed -i '/^#VAGRANT-END/i dns-nameservers 10.148.129.101' /etc/network/interfaces\n"
  f.write "systemctl restart networking.service\n"
  #f.write "rm -f /etc/resolv.conf\n"
  #f.write "ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf\n"
  #f.write "echo '      nameservers:'>>/etc/netplan/50-vagrant.yaml\n"
  #f.write "echo '        addresses: [10.148.129.101]'>>/etc/netplan/50-vagrant.yaml\n"
  #f.write "netplan apply eth1\n"
end

Uncomment the sed/systemctl for xenial, uncomment the later 5 lines for bionic.

You should have xenial/bionic boxs under ~/.vagrant.d/boxes.
