我有一個 Google Kubernetes Engine 正在運行，我正在嘗試部署一個 mongo 容器。一切正常，除非我嘗試使用引數“--wiredTigerCacheSizeGB”，然后部署失敗，因為無法識別此命令。我正在使用最新的 Mongo 版本 (5.0)，但我在檔案中沒有看到任何內容表明這不可行。
下面是POD創建的yml配置：

uj5u.com熱心網友回復：
如果你移除--wiredTigerCacheSizeGB標志，它會起作用嗎？
我會很驚訝。
它似乎確實有效（見下文），但我無法解釋原因。我很驚訝！
如果這是影像的正確Dockerfile，則它使用 DockerCMD運行mongod.
如果是這樣，您需要使用argsnotcommand在Kubernetes 上運行映像，以便正確覆寫容器映像CMD而不是覆寫容器映像ENTRYPOINT，即
containers:
- name: mongo
args:
- mongod
- --wiredTigerCacheSizeGB=2
注意
=在標志和值之間包含以避免引入 YAML 決議問題。
我使用以下方法測驗了這個假設podman；如果您使用，您可以在以下內容中替換podman為：dockerdocker
# Does not work: Override `ENTRYPOINT` with mongod flag
# This is effectively what you're doing
podman run \
--interactive --tty --rm \
--entrypoint="mongod --wiredTigerCacheSizeGB=2" \
docker.io/mongo:5.0 \
Error: executable file `mongod --wiredTigerCacheSizeGB=2` not found in $PATH:
No such file or directory:
OCI runtime attempted to invoke a command that was not found
# Works: Override `CMD`
# This is what I thought should work
podman run \
--interactive --tty --rm \
docker.io/mongo:5.0 \
mongod \
--wiredTigerCacheSizeGB=2
# Works: Override `ENTRYPOINT` w/ mongod
# This is what I thought wouldn't work
podman run \
--interactive --tty --rm \
--entrypoint=mongod \
docker.io/mongo:5.0 \
--wiredTigerCacheSizeGB=2
