我正在尝试按区域列出吊舱的
为此，我获取了节点的详细信息，其中它有区域详细信息和节点标识符，而pod列表有公共节点标识符，现在我想合并这两个结果，并希望按区域打印pod的区域。kubectl get nodes --label-columns failure-domain.beta.kubernetes.io/zone | awk '{print $1,$6}' | awk '{if (NR!=1) {print}}' | column -t > Nodes
kubectl get pods -n app -o wide | awk '{print $1, $7}' | column -t | awk '{if (NR!=1) {print}}' > pods
所需输出应类似
zone 1a
pod 1 nodename status region
pod 2 nodename status region
zone 1b
pod 1 nodename status region
pod 2 nodename status region
zone 1c
pod 1 nodename status region
pod 2 nodename status region
zone 2a
pod 1 nodename status region
pod 2 nodename status region
我试过的脚本，
# bash scrip to print pods in each zone
kubectl get nodes --label-columns failure-domain.beta.kubernetes.io/zone | awk '{print $1,$6}' | awk '{if (NR!=1) {print}}' | column -t > A
# get the pods list from app namespace
kubectl get pods -n app -o wide | awk '{print $1, $7}' | column -t | awk '{if (NR!=1) {print}}' > B
# Compare file A and B and list the pods in each zone
# > AB
cat A B
cat B | while read LINE;do
matching_col=$(echo "$LINE"| awk '{print $2}');
append_col=$(echo "$LINE"| awk '{print $1}');
cat A | grep $matching_col | head -1
if [[ $? -eq 0 ]]; then
line1="`cat A | grep $matching_col | head -1` ${append_col}"
echo $line1 >> AB
fi
done
# write the available zones list to C
cat AB | awk '{print $3,$6}' | column -t | sort > C
# compare A and B and list the pods in each zone, comparing C and A
for i in `cat C | awk '{print $1}'`; do
echo "pods in zone:" $i
kubectl get pods -n app -o wide | sed -n "/$i/p"
done
# delete the files
# rm AB
# rm A
# rm B
# rm C
