如何在kubernetes上部署映像后诊断服务

#!/usr/bin/env bash

set -euo pipefail
set -x

rootPath=".."
gcpProjectId="example123"
gcpRepoHostname="eu.gcr.io"
imageName="wordpress"
containerName="wordpress"
tagNameSuffix=$(date +%s)
tagNameSuffix="deploy-${tagNameSuffix}"
tagName="$gcpRepoHostname"/"$gcpProjectId"/"$imageName":$tagNameSuffix

echo "$GCLOUD_API_KEYFILE" | base64 --decode --ignore-garbage > ./gcloud-api-key.json
gcloud auth activate-service-account --key-file gcloud-api-key.json
gcloud config set project "$gcpProjectId"

sudo docker build "$rootPath"/wordpress/ -t "$tagName"
sudo gcloud docker -- push "$tagName"
kubectl set image deployment/wordpress "$containerName"="$tagName"

奇怪的是,当我修改 wordpress/Dockerfile

FROM rlesouef/alpine-nginx

如果我将其更改为:

FROM wordpress:php7.1-fpm-alpine

COPY custom-entrypoint.sh /usr/local/bin/

我得到了一个没有响应的服务-无法连接到外部ip。

kubectl get pods 显示以下内容:

NAME                        READY     STATUS    RESTARTS   AGE
wordpress-702001878-xb0b1   2/2       Running   0          8m

kubectl logs wordpress-702001878-xb0b1 wordpress :

[07-Aug-2017 15:13:14] NOTICE: fpm is running, pid 1
[07-Aug-2017 15:13:14] NOTICE: ready to handle connections

如何诊断此问题?我想我需要确定当前在集群/吊舱上运行的确切docker映像。
