SERVER SIDE / OPENSTACK
cloud.z.com에서 메모리 16기가의 가상머신을 준비했다.
on cloud.z.com, I prepared a virtual machine with 16GB RAM 50G disk.
네트웍은 글로벌 넷트웍하나, 프라이빗네트웍 하나를 준비했다. 글로벌이 eth0, 프라이빗이 eth1로 제공된다.
The network interfaces are two. one for global network and one for private network. the global is provided as eth0 and the private as eth1.
kolla-ansible을 사용해서 가상머신에 openstack 컴포넌트들을 설치했다. 순서는 다음의 qiita를 참고했는데,
I used kolla-ansible to install the openstack components on my virtual machine. I referred following qiita post;
kolla-ansibleでOpenStack(stable/queens)を構築する
여러번 반복해서 하다보니 ansible로 만들었다. 처음에 yum install python-pip -y && pip install ansible 로 시작하면 된다.
as I repeated the installation several times and made it ansible script finally. Start with yum install python-pip -y && pip install ansible.
anible파일을 kolla-rocky.yml로 저장한 다음 ansible-playbook kolla-rocky.yml로 실행한다.
You can save the anible file as kolla-rocky.yml and run it as ansible-playbook kolla-rocky.yml.
# yum install python-pip -y
# pip install ansible

위의 ansible은 kolla-ansible을 준비하고, 설정을 잡는 것 까지만 한다. 실제로 실행하는 kolla-ansible을 구동하는 코드는 다음과 같다.
The above is for preparation of kolla-ansible environment and configuration. Here is the code to run kolla-ansible which actually executes:
cd /opt && kolla-ansible -i all-in-one bootstrap-servers && kolla-ansible -i all-in-one prechecks && kolla-ansible -i all-in-one deploy && kolla-ansible post-deploy && source /etc/kolla/admin-openrc.sh && source /usr/share/kolla-ansible/init-runonce
OPENSTACK CLIENT SIDE
이쪽은 가상머신으로 윈도우즈를 선택했고, IDE는 pycharm을 설치했다.
I set a Windows virtual machine, and Pycharm IDE.
우선 conda 로 설치할 수 있는 것은 먼저 설치하고, 그렇지 못한 것들은 pip로 라이브러리를 설치했다.
I worked on the things I can install with conda first, and I installed the others with pip.

This script assumes that the following Python 2 packages are installed.
