iptable

container里ping不通外面

sudo iptables -t nat -A POSTROUTING -s  192.168.125.0/24 -o ens192 -j MASQUERADE

常用命令

# 删一条iptable
sudo iptables -t nat -D PREROUTING 1
# 删所有iptable
iptables -F -t nat
# 查看iptable
iptables -t nat -L --line-number | more

GCP container

快速進入docker的腳本

KEY=k8s_gcp  # gcp 换成 rpd

container_id=$(docker ps | grep $KEY | awk {'print $1'})
docker exec -it ${container_id} bash

debug

docker pull "dockerhub.cisco.com/cabu-cmts-orch-docker/gcp-service:debug"

設置debug模式

 1 kubectl get pods --all-namespaces
 2 kubectl exec --namespace=kube-system -it <robot-orch-container> bash
 3 # 进入orch container 后
 4 robotctl spec   - generates the new yaml file for the containers
 5 robotctl update – my guess updates pod.conf
 6 robotctl stop – stop existing default namespace containers, sometimes I needed to wait for few seconds till they stopped
 7 kubectl get pods --all-namespaces         --- check that all default namespace containers stopped
 8 robotctl start – start all containers
 9 kubectl get pods --all-namespaces         --- verify all containers RUNNING
10 # copy image
11 scp qingwyan@10.75.12.21:/home/qingwyan/workspace3/gcp-service/spring/target/gcp-service-0.1-SNAPSHOT.jar .
12 # 启动
13 java -jar -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5006 gcp-service-0.1-SNAPSHOT.jar

一條命令kill java進程

ps -ef | grep java | grep -v grep | awk {'print $2'} | xargs kill -9
# grep -v grep 过滤掉auto出现的进程号
