mongodb - 解析stateful.yaml时出错:将YAML转换为JSON时出错:yaml:第35行:在此上下文中不允许映射值

Question

我正在尝试在Kubernetes上部署mongodb，但出现错误:

error parsing stateful.yaml: error converting YAML to JSON: yaml: line 35: mapping values are not allowed in this context

第35行是容器名称:-名称: uat-mongo-primary

当我尝试创建Pod时出现此错误，但是如果我注释行:

mongo --eval rs.initiate({_id: "rs0", version: 1, members: [{ _id: 0, host : "uat-mongo-primary-rc-0:27017" }]}); 53 mongo --eval "db.getSiblingDB('admin').createUser({user : \"$MONGO_USER\", pwd : \"$MONGO_PASSWORD\", roles: [ { role: 'root', db: 'admin' } ] })";

可以正常创建的Pod，但我需要启动集群，还需要创建用户和密码。

这是我使用的完整yaml文件，我将不胜感激:

不能使用包含冒号的YAML字符串(至少在kubectl中使用)。您应该将YAML转换为JSON(例如，使用this工具)，然后将该JSON与kubectl一起应用。
