1、ingress-nginx,修改默认的Nginx上传大小:
使用Rancher的负载均衡,上传1M以上的文件报错,查看ingress-nginx容器,发现配置
client_max_body_size 1m;
解决办法:
创建ingress的时候修改参数:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
annotations:
nginx.ingress.kubernetes.io/proxy-body-size: 50m
2、k8s使用cronjob自动备份gitlab
常规情况为使用定时任务运行脚本,运行命令即可
gitlab-rake gitlab:backup:create
k8s中运行的gitlab,使用cronjob定时运行脚本即可:
1、为了可以使用kubectl,需要使用kubeconfig,创建configmap 就叫kubeconfig:
#kubeconfig默认放在/root/.kube/config
kubectl create configmap kubeconfig -n gitlab --from-file=/root/.kube/config
2、创建备份脚本,configmap:
备份脚本如下:
#!/bin/sh
pod_name=$(kubectl get pods -l app=gitlab -o jsonpath={.items[*].metadata.name} -n gitlab --kubeconfig=/etc/kubeconfig/config)
kubectl --kubeconfig=/etc/kubeconfig/config exec $pod_name -n gitlab -- gitlab-rake gitlab:backup:create
导入到configmap
3、挂载两个configmap,需要放到对应路径,kubeconfig放到/etc/kubeconfig/config,备份脚本放到运行路径下即可
4、配置cronjob定时运行挂载的脚本即可
