rebuild project with helm

Asked 2019-Nov-26 at 22:24

Unable to start build pods for helm project with helm

Hello,

I am wondering what is the best way to rebuild pods in a helm project on openshift. I am working with java S2i images on openshift 3.10 / 3.11. After updating my Java Code in my repository I would like to start builds.

Eventually I didn't find a solution to solve this problem. For a new deployment I set a timestamp inside the metadata of the deployment config.

So my question is how to trigger new build with helm? Is there a better way as oc start build ?

Thank you in advance,

Joern

Based on the information in the comments, I assume you need to set the correct trigger for your OpenShift image builds. The straight-forward approach seems to be to rebuild the image on every change in the repo. Therefore you should not explicitly state the commit in the BuildConfig and set a Webhook-Trigger from your code repo. For github, add this trigger to your BuildConfig:

Jenkins pipeline job checkout changed feature branch

Asked 2019-Nov-22 at 13:41

I have the following stage in my jenkins pipeline to get all branches of a project. I would like to trigger a build job, if one branch in project has changed on the changed branch.

First detect the changed branch and then checkout this specific branch out (I know that a webhook from bitbucket/github to jenkins would work.).

checkout all branches in project:

I propose to use a multibranch pipeline. This simplifies the work you would like to do. The multibranch pipeline keeps track of all your branches and builds only the ones that were changed. You can even filter out branches that doesn’t need a build (e.g. feature branches).

After this, you can select the relevant branches. You have multiple options to do this, now I attached one sample. In case the branch is not part of the selected branches list, then the pipeline will not start.

In your Jenkinsfile, you just have to write def scmVars = checkout scm. This command will clone the repository and checks out the branch that was changed.

QUESTION

Add vertical two finger swipe gesture to UIScrollView

Asked 2018-Nov-01 at 08:21

According to How to add a vertical swipe gesture to iPhone app for all screens, I add a two finger swipe down gesture to window, which works fine on normal pages throughout the whole app. But it fails on the page has UIScrollView (like UITableViewController). When I swipe down with two fingers on UIScrollView, it just scrolls it as normal. If I swipe from UINavigationBar that above UIScrollView, it works fine again.

The ideal result is that I can scroll tableview by one finger normally, and call some method by swiping page with two fingers without scrolling tableview. This is used in TweetBot to switch dark mode, works perfectly.

According to Apple's document: Using Responders and the Responder Chain to Handle Events, I think I understand how the Responder Chain works, so I want to ask UIScrollView to ignore the two fingers swipe gesture so that it can pass this event to UIWindow. But I can't figure out how to:

I tried to implement UIGestureRecognizerDelegate's func gestureRecognizer(_:, shouldRequireFailureOf otherGestureRecognizer:) from Apple's document, or override gestureRecognizerShouldBegin(_) by inherit UITableView. But all didn't work.

Any solutions or advice is welcomed.

When you add the UISwipeGestureRecognizer to your window, keep a reference to it, so you can access it later via the AppDelegate:

The slide gesture only show clear. Is there any settings for showing both clear and view

...

ANSWER

Answered 2017-Sep-05 at 06:20

The red and blue buttons are only available in iOS versions prior to iOS 10. With iOS 10 the notifications design changed. The slide gesture is used for the standard actions Clear and View. The custom actions Snooze and Confirm will be displayed when you force touch the notification or pull it down (for devices without force touch). If you are using a device with force touch the View button might not be shown.

The buttons look different now:

So, here is how you implement Local Notifications with Swift 3 / 4:

For iOS versions prior to iOS 10:

If you are supporting iOS versions prior to iOS10 you have to use the old (deprecated with iOS 10) UILocalNotification:

You most likely have a version of py2neo installed that is incompatible with Joern. If you used pip to install py2neo, you will get v3.x but Joern appears to only support v2.0 at the moment. Run the following command to confirm:

python -c "import py2neo; print py2neo.__version__"

If the above does not print 2.0, remove py2neo by running pip uninstall py2neo and then install v2.0 specifically by running pip install py2neo==2.0. Then re-test by running python -c "from py2neo.ext.gremlin import Gremlin" - it should complete without errors.
