有问题的 DevSpace-Django 教程如下：
https://devspace.cloud/blog/2019/10/18/deploy-django-to-kubernetes
尝试一些完全准系统的东西来了解如何devspace决定我是否要从skaffold. 上述教程中有许多内容似乎不再准确或在devpsace.
无论如何，当我导航到localhost:8000. 它只是说“无法连接到服务器”。
这是我得到的输出devspace dev：
devspace dev

Welcome to your development container!
This is how you can work with it:
- Run `python main.py` to build the application
- Files will be synchronized between your local machine and this container
- Some ports will be forwarded, so you can access this container on your local machine via localhost:
Image ImageSelector LabelSelector Ports (Local:Remote)
username/app 8000:8000
root@mysite-7b856bb78b-2ztpf-devspace:/app#
这是DevSpace.yaml：
version: v1beta10
# `vars` specifies variables which may be used as ${VAR_NAME} in devspace.yaml
vars:
- name: IMAGE
value: username/app
# `deployments` tells DevSpace how to deploy this project
deployments:
- name: mysite
# This deployment uses `helm` but you can also define `kubectl` deployments or kustomizations
helm:
# We are deploying the so-called Component Chart: https://devspace.sh/component-chart/docs
componentChart: true
# Under `values` we can define the values for this Helm chart used during `helm install/upgrade`
# You may also use `valuesFiles` to load values from files, e.g. valuesFiles: ["values.yaml"]
values:
containers:
- image: ${IMAGE} # Use the value of our `${IMAGE}` variable here (see vars above)
service:
ports:
- port: 8000
# `dev` only applies when you run `devspace dev`
dev:
# `dev.ports` specifies all ports that should be forwarded while `devspace dev` is running
# Port-forwarding lets you access your application via localhost on your local machine
ports:
- imageSelector: ${IMAGE} # Select the Pod that runs our `${IMAGE}`
forward:
- port: 8000
# `dev.open` tells DevSpace to open certain URLs as soon as they return HTTP status 200
# Since we configured port-forwarding, we can use a localhost address here to access our application
open:
- url: http://localhost:8000
# `dev.sync` configures a file sync between our Pods in k8s and your local project files
sync:
- imageSelector: ${IMAGE} # Select the Pod that runs our `${IMAGE}`
excludePaths:
- .git/
uploadExcludePaths:
- Dockerfile
# `dev.terminal` tells DevSpace to open a terminal as a last step during `devspace dev`
terminal:
imageSelector: ${IMAGE} # Select the Pod that runs our `${IMAGE}`
# With this optional `command` we can tell DevSpace to run a script when opening the terminal
# This is often useful to display help info for new users or perform initial tasks (e.g. installing dependencies)
# DevSpace has generated an example ./devspace_start.sh file in your local project - Feel free to customize it!
command:
- ./devspace_start.sh
# Since our Helm charts and manifests deployments are often optimized for production,
# DevSpace let's you swap out Pods dynamically to get a better dev environment
replacePods:
- imageSelector: ${IMAGE} # Select the Pod that runs our `${IMAGE}`
# Since the `${IMAGE}` used to start our main application pod may be distroless or not have any dev tooling, let's replace it with a dev-optimized image
# DevSpace provides a sample image here but you can use any image for your specific needs
replaceImage: loftsh/python:latest
# Besides replacing the container image, let's also apply some patches to the `spec` of our Pod
# We are overwriting `command` + `args` for the first container in our selected Pod, so it starts with `sleep 9999999`
# Using `sleep 9999999` as PID 1 (instead of the regular ENTRYPOINT), allows you to start the application manually
patches:
- op: replace
path: spec.containers[0].command
value:
- sleep
- op: replace
path: spec.containers[0].args
value:
- "9999999"
- op: remove
path: spec.containers[0].securityContext
# `profiles` lets you modify the config above for different environments (e.g. dev vs production)
profiles:
# This profile is called `production` and you can use it for example using: devspace deploy -p production
# We generally recommend to use the base config without any profiles as optimized for development (e.g. image build+push is disabled)
- name: production
# This profile adds our image to the config so that DevSpace will build, tag and push our image before the deployment
merge:
images:
app:
image: ${IMAGE} # Use the value of our `${IMAGE}` variable here (see vars above)
dockerfile: ./Dockerfile
这是Dockerfile：
FROM python:3.8-slim-buster
# Create project directory (workdir)
WORKDIR /app
# Add requirements.txt to WORKDIR and install dependencies
COPY requirements.txt .
RUN pip install -r requirements.txt
# Add source code files to WORKDIR
ADD . .
# Application port (optional)
EXPOSE 8000
# Container start command
# It is also possible to override this in devspace.yaml via images.*.cmd
CMD ["manage.py", "runserver", "8000"]
DevSpace UI 和kubectl get pods显示 Pod 正在运行。
这是部署到minikube使用 Docker 驱动程序。
端口上没有其他任何东西在运行8000，我也尝试8080通过更改每次出现的8000to 8080。
Django 项目只是您在运行时得到的：django-admin startproject mysite. 没有什么花哨。
我不清楚我在这里做错了什么。建议？
编辑：
此外，意在指出 M1 Mac。不确定它是否相关但值得指出。
尝试使用docker-desktop集群并minikube认为这可能是minikube. 同样的问题。
此外，使用 DevSpace 提供的项目尝试了此处的快速入门指南，结果相同：
