GCP Kubernetes 找不到 Elixir Dockerfile 项目的 libgcc_s
GCP Kubernetes doesn't find libgcc_s for a Elixir Dockerfile project
上下文
目前第一次在 Google Cloud 和 Kubernetes 上发布 Elixir/Phoenix 应用程序，（我找到了一个教程，我按照教程 => run an Elixir/Phoenix app in containers using Google Kubernetes Engine), I'm getting stuck at what seems to be the last step : Deploy to the cluster 由于一些错误我还没有找到解决办法。
应用程序
elixir 应用程序是一个 umbrella 应用程序，有两个 phoenix 应用程序，每个都有一个端口（用于管理网站，另一个用于一般网站）和其他三个 elixir应用
dev有一个自定义的docker（使用docker-compose），还有一个Dockerfile for production，就是下面这个（分开分为两部分，我想第一部分是用于图像构建，第二部分是用于 kubernetes):
# prod.Dockerfile
FROM elixir:alpine
ARG app_name=prod
ARG phoenix_subdir=.
ARG build_env=prod
RUN apk add --no-cache make build-base openssl ncurses-libs libgcc libstdc++
ENV MIX_ENV=${build_env} TERM=xterm
WORKDIR /opt/app
RUN apk update \
&& apk --no-cache --update add nodejs npm \
&& mix local.rebar --force \
&& mix local.hex --force
COPY . .
RUN mix do deps.get, compile
RUN cd apps/admin/assets \
&& npm rebuild node-sass \
&& npm install \
&& ./node_modules/webpack/bin/webpack.js \
&& cd .. \
&& mix phx.digest
RUN cd apps/app/assets \
&& npm rebuild node-sass \
&& npm install \
&& ./node_modules/webpack/bin/webpack.js \
&& cd .. \
&& mix phx.digest
RUN mix release ${app_name} \
&& mv _build/${build_env}/rel/${app_name} /opt/release \
&& mv /opt/release/bin/${app_name} /opt/release/bin/start_server
FROM alpine:latest
RUN apk add make build-base --no-cache openssl ncurses-libs libgcc libstdc++
ARG hello
RUN apk update \
&& apk add --no-cache postgresql-client \
&& apk --no-cache --update add bash ca-certificates openssl-dev \
&& mkdir -p /usr/local/bin \
&& wget https://dl.google.com/cloudsql/cloud_sql_proxy.linux.amd64 \
-O /usr/local/bin/cloud_sql_proxy \
&& chmod +x /usr/local/bin/cloud_sql_proxy \
&& mkdir -p /tmp/cloudsql
ENV GCLOUD_PROJECT_ID=${project_id} \
REPLACE_OS_VARS=true
EXPOSE ${PORT}
EXPOSE 4011
WORKDIR /opt/app
COPY --from=0 /opt/release .
CMD (/usr/local/bin/cloud_sql_proxy \
-projects=${GCLOUD_PROJECT_ID} -dir=/tmp/cloudsql &); \
exec /opt/app/bin/start_server start
由 cloudbuild.yaml:
调用
steps:
- name: "gcr.io/cloud-builders/docker"
args: ["build", "-t", "gcr.io/hello/prod:$_TAG",
"--build-arg", "project_id=hello", ".",
"--file=./prod.Dockerfile"]
images: ["gcr.io/hello/prod:$_TAG"]
步骤
（重新）构建图像
$> gcloud builds submit --substitutions=_TAG=v1 .
然后创建部署
$> kubectl run hello-web --image=gcr.io/${PROJECT_ID}/hello:v1 --port 8080
pod/hello-web created
检查部署是否顺利（剧透：不顺利）
$> kubectl get pods
NAME READY STATUS RESTARTS AGE
hello-web 0/1 CrashLoopBackOff 1 15s
查看日志
$> kubectl logs {POD-NAME}
其中显示如下错误：

我尝试了什么
虽然我几乎一无所知，但我还是试着修改了一点Dockerfile，但没有成功。我还搜索了 Google libgcc 错误，但没有成功。
就是这样，因为我没有其他线索可以查看。
那么，有什么建议可以让它发挥作用吗？
其他操作
删除 pod，然后获取图像的标签并清理它
$> kubectl delete pod hello-web
$> gcloud container images list-tags gcr.io/hello/prod
$> gcloud container images delete gcr.io/hello/prod@sha256:...

- 用最新版本更新 Dockerfile
- 再添加一个动作列表
结果：没有改变
看来您的问题已经在 Elixir 论坛上提出过：
It looks like a missing runtime dependency in your final image. Try changing RUN apk add --no-cache openssl ncurses-libs to RUN apk add --no-cache openssl ncurses-libs libstdc++.
解决方法是将 libstdc++ 添加到您的安装行。
论坛中也概述了这样做的原因 post:
The beam has native runtime dependencies and OTP 24 added libc as runtime dependency to support the JIT. With that change it seems like bare alpine:3.9 no longer brings all the required runtime dependencies. You’ll need to make sure that all of those those are present in the app container.
祝你好运！
因此，经过数小时的测试和尝试，我只是改变了策略并专注于图像版本而不是 Dockerfile。
$> gcloud builds submit --substitutions=_TAG=v1.1 .
$> kubectl run hello-web --image=gcr.io/${PROJECT_ID}/hello:v1.1 --port 8080
我之前没有更改它，因为我想在构建和应用程序之间保持相同的版本。
我更改的另一件事是 cloudbuild.yaml：我删除了名称前面的破折号。
这两个操作在 pod 中构建了 运行。
