I have a Dockerfile
that looks something like the following:
ANSWER
Answered 2021-Nov-01 at 17:32You could use the appendDockerfileInstructions
option in combination with multi-stage builds (i.e. multiple FROM
statements in the Dockerfile added in-memory via devspace): https://devspace.sh/cli/docs/configuration/images/append-dockerfile-instructions

I'm getting this error in my PR pipeline and I'm not sure what the cause and solution is.
The Docker task is pretty well templated and the stage does exist in my Dockerfile

ANSWER
Answered 2021-Oct-04 at 07:02Yes, you should be using the after:initialSync:*
hook, i.e. if your sql dump file is part of the file sync, it will be uploaded during initialSync, then the hook can be used to import the dump.

My ultimate goal is to have tests run automatically anytime a container is updated. For example, if update /api
, it should sync the changes between local and the container. After that it should automatically run the tests... ultimately.
I'm starting out with Hello World!

Answered 2021-Oct-02 at 05:55You will need a post-sync hook for this, which is separate from the DevSpace lifecycle hooks. You can define it with the dev.sync
directly and it looks like this:

QUESTION
I've been toying with DevSpace with Helm charts and possibly migrating to it from Skaffold and Kubernetes manifests. I can't seem to get the ingress controller working for local development: comes back with 404 Not Found
. I can reach it via port-forwarding, however, at localhost:3000
.
Like I've always done, I installed the ingress-nginx
controller first for docker-desktop

ANSWER
Answered 2021-Sep-16 at 21:44To debug this, you may want to run devspace render
which shows the plain manifests that DevSpace generates from the Helm chart before deploying them to the cluster. That way you can see what is different compared to your skaffold manifests. Alternatively, you could check inside the cluster using these commands:

The DevSpace-Django tutorial in question is the following:
https://devspace.cloud/blog/2019/10/18/deploy-django-to-kubernetes
Trying something completely barebones to understand how devspace
works to decide if I want to make the switch from skaffold
. There are a number of things in the above tutorial that seem to be no longer accurate or have changed in more recent versions of devpsace

At any rate, I'm not able to connect to the Django tutorial app when I navigate to localhost:8000

This is the output I get when I devspace dev

QUESTION
I'm deploying several services to my local cluster (minikube
) using DevSpace tool. Once someone makes changes to one of the services and pushes the image to our private repo, I need these changes to be available on my local then. What I do now is I completely delete minikube
cluster and start a new one. In this case all images with same tags are just updated with the latest version, not a cached one.
But I believe there is some more elegant way to overcome this. So, I need to cleanup/remove/delete outdated images from my local cluster somehow before re-deploying services there.
Can someone point where they are stored, how I can review and remove them? Thanks.

QUESTION
There are a few processes I'm struggling to wrap my brain around when it comes to multi-stage Dockerfile
.
Using this as an example, I have a couple questions below it:
...ANSWER
Answered 2021-Aug-10 at 17:01Copying my response to this from Reddit to help others who may look for this on StackOverflow:
DevSpace maintainer here. For my workflow (and the default DevSpace behavior if you set it up with devspace init
), image building is being skipped during development because it tends to be the most annoying and time-consuming part of the workflow. Instead, most teams that use DevSpace have a dev image pushed to a registry and build by CI/CD which is then used in devspace.yaml
using replacePods.replaceImage
as shown here: https://devspace.sh/cli/docs/configuration/development/replace-pods
This means that your manifests or helm charts are being deployed referencing the prod images (as they should be) and then devspace will (after deployment) replace the images of your pods with dev-optimized images that ship all your tooling. Inside these pods, you can then use the terminal to build your application, run tests along with other dependencies running in your cluster etc.
However, typically teams also start using DevSpace in CI/CD after a while and then they add profiles
(e.g. prod
profile or integration-testing
profile etc. - more on https://devspace.sh/cli/docs/configuration/profiles/basics) to their devspace.yaml
where they add image building again because they want to build the images in their pipelines using kaniko or docker. For this, you would specify the build target in devspace.yaml
as well: https://devspace.sh/cli/docs/configuration/images/docker#target
FWIW regarding 1: I never use docker run --target
but I also always use Kubernetes directly over manual docker commands to run any workloads.
