magnum安装
安装条件：
- 至少要10G以上内存的机器。亲测使用6G的虚拟机，所有操作均有至少一秒延迟。
- 硬盘至少50G
- 良好的上网环境
操作步骤参见快速入门
以下是我操作的步骤记录
sudo mkdir -p /opt/stack
sudo chown $USER /opt/stack
git clone https://git.openstack.org/openstack-dev/devstack /opt/stack/devstack
我的local.conf样例
[[local|localrc]]
HOST_IP=10.8.65.216
FIXED_RANGE=10.24.0.0/24
NETWORK_GATEWAY=10.24.0.1
SERVICE_TOKEN=azertytoken
ADMIN_PASSWORD=xxkxxkxxk
DATABASE_PASSWORD=xxkxxkxxk
RABBIT_PASSWORD=xxkxxkxxk
SERVICE_PASSWORD=xxkxxkxxk
PUBLIC_INTERFACE=eth0
enable_plugin magnum https://git.openstack.org/openstack/magnum
LOGFILE=$DEST/logs/stack.sh.log
LOGDAYS=2
enable_service tempest
disable_service n-net
enable_service q-svc
enable_service q-agt
enable_service q-dhcp
enable_service q-l3
enable_service q-meta
执行安装。由于网络问题，经常下包失败，所以失败时候手动安装部分包或者重新执行stack.sh
cd /opt/stack/devstack
./stack.sh
运行magnum
创建flavor
stack@magnum:~/devstack$ nova flavor-create m1.1g 11 1024 20 1

创建pod
首先编写manifest
[root@A01-R06-I141-86 mysql]# cat mysql.yaml
apiVersion: v1
kind: Pod
metadata:
labels:
name: mysql
role: master
name: mysql-pod
spec:
containers:
- name: master
image: index.alauda.cn/tutum/mysql:5.5

通过命令创建pod
magnum pod-create --bay k8sbay --manifest mysql.yaml
