编辑配置文件
1、变更etcd的配置
修改Secret的配置,其中etcd-key、etcd-cert、etcd-ca是将etcd的证书及私钥等使用下面命令输出为base64字符串,实际输出的字符串长度会远大于示例中字符串长度(只截取部分用于示例)。注意,字符串必须去掉回车变为整行显示,否则会导致插件无法安装成功。
# 这条命令的意思是输出ca证书等信息,转换成base64并使用一行显示(删除回车)
cat /etc/etcd/cert/ca.pem | base64 | tr -d '\n'
cat /etc/etcd/cert/kubernetes.pem | base64 | tr -d '\n'
cat /etc/etcd/cert/kubernetes-key.pem | base64 | tr -d '\n'
示例如下:
guide/secrets/
apiVersion: v1
kind: Secret
type: Opaque
metadata:
name: calico-etcd-secrets
namespace: kube-system
data:
# Populate the following with etcd TLS configuration if desired, but leave blank if
# not using TLS for etcd.
# The keys below should be uncommented and the values populated with the base64
# encoded contents of each file that would be associated with the TLS data.
# Example command for encoding a file contents: cat <file> | base64 -w 0

2、修改calico-config配置,为calico配置etcd
我的etcd证书放在了集群节点的/etc/etcd/cert目录下,请根据自己的目录进行变更,但是注意文件夹名(calico-secrets)及各个文件名(etcd-ca、etcd-cert 、etcd-key)不能变更,因为这些文件夹名及文件名已经在calico.yaml的配置文件中定义了。
mkdir /calico-secrets && cd /calico-secrets
cp /etc/etcd/cert/ca.pem etcd-ca
cp /etc/etcd/cert/kubernetes.pem etcd-cert
cp /etc/etcd/cert/kubernetes-key.pem etcd-key
chmod 0400 /calico-secrets/etcd*
示例如下:
kind: ConfigMap
apiVersion: v1
metadata:
name: calico-config
namespace: kube-system
data:
# Configure this with the location of your etcd cluster.
etcd_endpoints: "https://192.168.2.21:2379,https://192.168.2.22:2379,https://192.168.2.23:2379"
# If you're using TLS enabled etcd uncomment the following.
# You must also populate the Secret below with these files.
etcd_ca: "/calico-secrets/etcd-ca" # "/calico-secrets/etcd-ca"
etcd_cert: "/calico-secrets/etcd-cert" # "/calico-secrets/etcd-cert"
etcd_key: "/calico-secrets/etcd-key" # "/calico-secrets/etcd-key"
# Typha is disabled.
typha_service_name: "none"
# Configure the backend to use.
calico_backend: "bird"
3、配置calico工作模式及网络
注意其中红字的部分,增加了网卡匹配规则,防止calico默认找错网卡,并且更改calico的工作模式。其中interface=ens18表示匹配ens18网卡,也可以使用正则表达式,如【ens.*——匹配ens开头的网卡】,这里,我们用“Never”禁用掉IPIP模式,则会使用BGP模式。
CALICO_IPV4POOL_CIDR的配置一定要与pod的网络保持一致,如podSubnet的配置是10.30.0.0/24,那么CALICO_IPV4POOL_CIDR的值也必须为10.30.0.0/24。

kubectl get pods -n kube-system
kubectl describe pod xxx -n kube-system
kubectl logs xxx -n kube-system
有些时候查看pod是无法查看出真正的错误原因,这时需要我们使用crio的相应操作直接查看启动的容器,查看出相应的错误后进行相应的解决。
crictl ps -a
crictl logs xxx(容器id)
