cron-job | php实现的秒级定时任务工具，基于workerman的库 | Cron Utils library

I installed Docker on a CentOS 7 machine and DNS is not working within containers.

So, if I run nslookup google.com on my host, it resolves correctly. However, if I do docker container run busybox nslookup google.com I get:

So I've a cron job like this:

I am trying to deploy my first cron job.

Starting with a very simple one, as described in the k8s tutorial:

I have built a command line interface using Python's click library (version 7.1.2) that can run a command that asks the (human) user to answer certain confirmations on the way (The well known "Are you sure you want to continue? Y/n")

Now, I'm trying to run that command automatically on a Kubernetes CronJob and I need a way of "pretending" to input Y to each of the prompts.

I have seen the click.confirmation_option, but if I understand correctly, that seems more like a confirmation to run the whole command, right? (maybe I'm wrong?)

I'm more looking for something like some kind of assume_yes in the example below (could be passed either to the invocation or when creating full context ctx = cli.make_context...):

Running a k8 cronjob on an endpoint. Test works like a charm locally and even when I sleep infinity at the end of my entrypoint then curl inside the container. However once the cron kicks off I get some funky error:

I have a major problem and will do my best to be short in the explanation. I am running a cronjob on an endpoint and would like to containerize that process. The endpoint needs to have some environments variables set and obviously a TOKEN authentication which is basically the login before I can curl POST or GET to get what I want from the API. The tricky part is that that TOKEN is never the same which means I need to run a curl command to get it during the pod run time. To make sure those environments variables are there in run time I injected a command in the cronjob args field to keep it running. When I ssh to the pod all my all env var are there ;) but the TOKEN :( . When I run ./run.sh from inside the pod nothing happens which is the reason the TOKEN isn't listed in printenv. However when I manually run command 1 then command 2 from inside the pod it works fine. I am very confused and please help me if you can please. Instead of running my commands as a bash in the cmd at the docker level, I have seen that I can possibly parse command 1 and command 2 from the run.sh inside my cronjob.yaml with a multi line block scalar but haven't figured how as yaml format are a pain. Below are my codes for more details:

docker-entrypoint.sh --> removed

I use youtube-dl to archive specific blogs. I use a custom bash script (called tvify) to help me organize my content into Plex-ready filenames for later replay via my home Plex server.

Archiving the content works fine, unless a blogger posts more than one video on the same date - if that happens my script creates more than one file for a given month/date and plex sees a duplicate episode. In the plex app, it stuffs them together as distinct 'versions' of the same episode. The result is that the description of the video no longer matches its contents, and only one 'version' appears unless I access an additional sub menu.

The videos get downloaded by you tube-dl kicked off from a cron-job, and that downloader script runs the following to help format their filenames and stuff them into appropriate folders for 'seasons'.

The season is the year when the video was released, and the episode is the combination of the month and date in MMDD format.

Below is my 'tvify' script, which helps perform the filename manipulation and stuffs the file into the proper folder for the season.

As simple it can sounds I am just trying to append these 2 commands below as arguments in my pod during run time. I tested those 2 commands by going inside the pod and running them manually and it worked like a charm. I am just trying to inject those commands inside the cronjob yaml and been scratching my head. Haven't found the right way.

Command 1

I need to implement regex validation for value that will be used in my server side to get data where certain timestamp is older (smaller) than now() - interval 'myValue'.

pSQL interval function is explained here, and in short it can have values like 2 days,3 years,12 hours, but also you can nest more different values like 2 days 6 hours 30 minutes etc.

I currently have a regex /^\d+\s(seconds?|minutes?|hours?|days?|weeks?|months?|years?)$/i that accepts only one value (e.g. 2 days), but can't figure out how to allow multiple values, and set a rule that a certain string from this group can only be repeated once or not at all.

This regex /^\d+\s(seconds?|minutes?|hours?|days?|weeks?|months?|years?)(\s\d+\s(seconds?|minutes?|hours?|days?|weeks?|months?|years?))*$/i allows nesting but also allows repetition of values e.g. 2 days 12 hours 6 hours 2 minutes which will result in a fatal error in pSQL query.

I tried restricting repetition of values in this group with \1 and {0,1} combination of regex operators but I just can't nail it precisely enough.

NOTE: Regex is unfortunately only way I can validate this value, since I don't have access to server-side controller which receives this value nor do I have access to client-side frontend of this form. I can't just throw exceptions or skip query because it is a part of important cron-job, and must be stable at all time.

(All I have access to is json schema of this value, and therefore can only define regex pattern for it)

Any help is appreciated, thanks.
