QUESTION
I'm attempting to take advantage of Spring Cloud Kubernetes in my Spring Boot-based microservice, namely autoconfiguration and service discovery.
However, I get an error message (Timeout waiting for informers cache to be ready, is the kubernetes service up?) during the initialization, as well as high verbosity, both of which I am unable to find information online to help me pinpoint the cause. Error message and excessive log messages are detailed below. Apologies for the lack of context, but I'm also puzzled!
The application is running within the default service account, which has all the permissions specified in the documentation:
ANSWER
Answered 2021-Apr-18 at 17:01You need to grant neccessary permissions to your spring app, with dependency spring-cloud-starter-kubernetes-fabric8-all that you're using, you will need to grant these permissions: "configmaps", "pods", "services", "endpoints", "secrets".
Below is an example from Spring Cloud document :
QUESTION
I'm trying to create [1] AWS V4 signed URLs to download files stored in a ScaleWay Object Storage bucket. I used the python example from AWS's [2] site and modified it but I can't make it work. When I try to access the generated link, I get a 403 response [3] which you can see below.
I copy my python script [4] here that produces the 403 links.
Could you please take a look at it and let me know what I did wrong? Why can't I generate the proper signature?

Answered 2021-Jan-21 at 00:36If you use a GET request, you shouldn't use the hash of an empty string (like it is told in the official example) for the canonical request but the raw "UNSIGNED-PAYLOAD" string.
As an example:
Your canonical request will look like this:

QUESTION
I recently created a S3 bucket at Scaleway. I mount it using s3fs without apparent problem. I have problems uploading some "mid size" files. If the size under 20 M it's ok but for with larger files (50 M and more), the copy fails with message "unable to write file, permission denied". I contacter scaleway support but they said it's related to my s3fs client. I mounted the bucket in debug mode, using :
...ANSWER
Answered 2020-May-02 at 18:28From where do you mount your bucket? Is it your PC in your home or a cloud VM? How much time does it take before you receive this error?
I'm asking because "SSL_write() returned SYSCALL, errno = 32" looks like something is closing your connection. "HTTP error before end of send, keep sending" also points for that kind of problem. A timeout maybe occurs? Do you have a NAT gateway between you and your bucket? That can also cause the problem, if it does not care about keepalives as the upload can take relatively long.
As the s3fs wiki says, 20MB is the threshold for multipart uploads instead of single request. Maybe Scaleway has a slightly different API for multipart uploads than Amazon? From the s3fs wiki: "Some providers do not support the full S3 API, e.g., lacking multi-part upload." Please make note that s3fs is mainly intended to work with Amazon S3 and, as I see, Scaleway is not on the list of supported providers in the s3fs wiki: https://github.com/s3fs-fuse/s3fs-fuse/wiki/Non-Amazon-S3.
The last thing, what's your version of libcurl? The s3fs documentation says it should be 7.16 or 7.17. And are you using the latest version of s3fs?

I am unable to debug code or run a Python console due to an inability to import ssl. I get this behavior when using two Anaconda virtual environments I have created.

ANSWER
Answered 2019-Feb-09 at 19:01I encountered the same issue with PyCharm recently. Based on their forum post it's a known issue that will be fixed in the next release of Pycharm 2019.1. The only way that I have found to get around this is to create an environment using python 3.6. If you use that environment as your interpreter PyCharm should work properly. Hope this helps.
QUESTION
Background: To give a bit of background ⇒ the app should simply show the user an area (SignatureActivity / SignatureCanvasView) to put a signature. I found a snippet, which works pretty well to draw in.
Issue: Trying to retrieve the bitmap in the MainActivity to show it in an ImageView shows an empty Image. Also writing the retrieved Bitmap creates an png file, which is pretty much empty, since it has even not a background color.
That's how it's done in MainActivity:

Answered 2020-Feb-20 at 08:56You are drawing Path onto canvas attached with SignatureCanvasView, not on the canvas attached with Bitmap mBitmap.
QUESTION
I'm trying to implement a GitLab continuous integration (CI) pipeline with the following .gitlab-ci.yml file:
ANSWER
Answered 2017-Feb-19 at 02:07This is complex problem.
The docker:latest image is based on alpine (Alpine Linux), which is built using musl-libc. This system is very barebones, and as such doesn't have everything a full-fledged desktop Linux might have. In fact, dynamic executables need to be compiled specifically for this system.
docker-compose is a Python application, bundled into a Linux executable using PyInstaller. These executables are really only expected to be able to run on the system which they were built. If you run an alpine container, and apk add file, you can see that the (dynamically-linked) executable you downloaded is expecting a specific interpreter.
