[英]Pulumi modify kubernetes resource based on selected stack
what is the best way to modify kubernetes containers based on which stack is selected?根据选择的堆栈修改 kubernetes 容器的最佳方法是什么? I see that Input types cannot be modified.我看到无法修改输入类型。 I've found the spread operator eg:我找到了扩展运算符,例如:
const ledgerDeployment = new k8s.extensions.v1beta1.Deployment("ledger", {
metadata: {
namespace: ledgerNamespace.metadata.name,
},
spec: {
template: {
metadata: {
labels: {name: "ledger"},
},
spec: {
containers: [
// containers
],
volumes: [
{
//volume 1
},
{
// volume 2
},
// conditional volume based on the stack
...(stack == 'dev' ? [{
name: dbTLS.metadata.name,
secret: {secretName: dbTLS.metadata.name, defaultMode: 256}
}] : [])
]
}
}
}
});
but that feels kinda icky and in my opinion adds complexity to large resource declarations (especially as the conditionals become more complex).但这感觉有点恶心,在我看来,这增加了大型资源声明的复杂性(尤其是当条件变得更加复杂时)。 I've tried pulling out the container definition into a variable but since I can't declare the type of the variable I'm having some problems with assigning an Output
to one of the keys in the variable:我尝试将容器定义提取到变量中,但由于我无法声明变量的类型,因此在将Output
分配给变量中的一个键时遇到了一些问题:
let apiContainer = {
name: "api",
image: appImage.imageName,
// more stuff ...
volumeMounts: [
{
mountPath: "/app/gunicorn-socket",
name: "gunicorn-socket-dir",
readOnly: false
},
],
}
if (stack != 'local') {
apiContainer.volumeMounts.push({
mountPath: "/etc/secret/db",
name: dbTLS.metadata.name,
readOnly: true
})
}
Gives an error on name
with Type 'Output<string>' is not assignable to type 'string'
.在name
上出现错误, Type 'Output<string>' is not assignable to type 'string'
。
It seems that the interface is exported on github for tag 1.4.5
but when I view the interface locally it's not exported:似乎接口是在 github 上为标记1.4.5
导出的,但是当我在本地查看接口时,它没有导出:
12:41PM /Users/paymahn/qwil/ledger/pulumi/infra pulumi ⬆ ⬇ ✱ ➜

I've verified that I'm on v1.4.5 locally:我已经确认我在本地使用 v1.4.5:

The types are available, maybe you are looking at a wrong package.类型可用,也许您正在查看错误的包。 Eg k8s.types.input.core.v1.Container
is the right type name.例如k8s.types.input.core.v1.Container
是正确的类型名称。
To dynamically build a collection of volume mounts, it's easiest to operate with arrays of mounts directly:要动态构建卷挂载的集合,最简单的方法是直接使用挂载数组:
const volumeMounts: k8s.types.input.core.v1.VolumeMount[] = [{
mountPath: "/app/gunicorn-socket",
name: "gunicorn-socket-dir",
readOnly: false
}];
if (stack != 'local') {
volumeMounts.push({
mountPath: "/etc/secret/db",
name: dbTLS.metadata.name,
readOnly: true
});
}
const apiContainer: k8s.types.input.core.v1.Container = {
name: "api",
image: appImage.imageName,
volumeMounts,
};
Had you declared an instance of k8s.types.input.core.v1.Container
, now volumeMounts
property would be not an array but an input of array, so you'd have to convert it to output, apply, create a new array, and assign back.如果您声明了k8s.types.input.core.v1.Container
的实例,现在volumeMounts
属性将不是数组而是数组的输入,因此您必须将其转换为输出,应用,创建一个新数组,并分配回来。
