I have a pair of plans setup in Bamboo 5.8, let's call them plan A (smoke test) and plan B (full build and deploy). Plan A is the parent and is set to trigger the child, plan B, with no other advanced or blocking strategies setup on the Dependencies tab. Plan B is only triggered as a child of plan A, no other triggers are enabled. The problem I am seeing is that if plan B is already running and then a second plan A is triggered and finishes before the first plan B completes, when plan B finally finishes, it doesn't get triggered to run by the second plan A , it just sits there until a third plan A happens to be kicked off.
I'm not seeing any way to 'retry' a dependency trigger if the child plan is busy/currently building, is there something server side that needs to be changed or refreshed? We only have 3 build agents.
I'm also experiencing this issue. There is an eight year old, still open Atlassian support ticket for this: BAM-2820. Their workaround in there is to run concurrent builds, which doesn't work in my case because our builds use a shared resource.

I've written a .NET Core Rest API which does migrate/ update the database (using Entity Framework Core) in Startup.cs. Currently, only one instance is running in the production environment. It seems to be recommended to run 2 instances in production.
What happens while executing the cf push command? Are both instances stopped automatically or do I need to execute cf stop?
In addition, how do I prevent both instances from updating the database?
I've read about the CF_INSTANCE_INDEX environment variable. Is it OK to only start the database migration when CF_INSTANCE_INDEX is 0? Or does CloudFoundry provide the next mechanism: start the first instance and when this one is up-and-running, the second instance will be started?

Yes, your app will stop. The new code will stage (i.e. buildpacks run) and produce a droplet. Then the system will bring up all the requested instances using the new droplet.

You can certainly do it that way. The instance number is guaranteed to be unique and the zeroth instance will always exist, so if you limit to the zeroth instance then it's guaranteed to only run once.
Another option is to run your migration as a task (i.e. cf run-task). This runs in its own container, so it would only run once regardless of the number of instances you have. This SO post has some tips about running a migration as a task.
Or does CloudFoundry provide the next mechanism: start the first instance and when this one is up-and-running, the second instance will be started?
It does, it's the --strategy=rolling flag for cf push.
See https://docs.cloudfoundry.org/devguide/deploy-apps/rolling-deploy.html
I'm not sure that this feature would work for ensuring your migration runs only once. According to the docs (See "How it works" section at the link above), your new and old containers could overlap for a short period of time. If that's the case, running the migration could potentially break the old instances. It'll be a short period of time, just until they get replaced with new instances, but maybe something to consider.
When using Google Cloud Tasks, how can i prematurely run a tasks that is in the queue. I have a need to run the task before it's scheduled to run. For example the user chooses to navigate away from the page and they are prompted. If they accept the prompt to move away from that page, i need to clear the queued task item programmatically.
I will be running this with a firebase-function on the backend.
Looking at the API for Cloud Tasks found here it seems we have primitives to:
list - get a list of tasks that are queued to run
delete - delete a task this is queued to run
run - forces a task to run now
Based on these primitives, we seem to have all the "bits" necessary to achieve your ask.
For example:
To run a task now that is scheduled to run in the future.
List all the tasks
Find the task that you want to run now
Delete the task
Run a task (now) using the details of the retrieved task
We appear to have a REST API as well as language bound libraries for the popular languages.
We have most, but not all of our build artifacts into a Git repo (Bitbucket).
Our current build looks like this, and takes 30+ minutes to build/deploy to Firebase, we would like to reduce the time to build.
We are not using Google Cloud Build at the moment, but before heading down that path, I want to find out if that would even be fruitful.
We have all of the code cloned from the git repo (Bitbucket), to a GCE VM.
And then 1 TB of static data is then copied into a directory under the git repo area, artifacts that are needed for the deploy.
We do not want to check in that 1TB of data into the git repo, it is from a 3rd party, it is rarely updated, and would be too heavy of a directory to pull into developer environments on their IDE's, it is pointless to do so.
We launch a build script on the GCE VM to build the code, and deploy to Firebase (bash script), it takes about 30 minutes.
We want the builds to go faster, and possible to use cloud build.
With this:
a git repo
external files that need to remain in a stateful container, not copied over each time, due to the time it would take
how do we create a stateful container that would only require a git update (pull origin master), and then to fire off a build/deploy to Firebase?
We want to avoid ingress traffic to the Firebase deploy using external build services where the 1TB of data that remains the same each and every time is sent to Firebase, where we would be billed.
Cloud Run containers are not stateful. GCE VM's are stateful, but it requires that we keep them up and going 24x7x365, so that any developer anywhere can run a build, and that may take only 30 minutes out of any day, and we don't know when that will be, so leaving it up 24x7x365 is mostly wasteful.
We want to avoid building a stateless container where the code is checked out fresh each and every time, a git pull origin master will do, and to have to copy the 1TB of artifacts into the container each and every time taking time.
We just want to do:
git pull origin master
Fire off the build as the next step in the script
spin down the container, have it save it's state for the next build, minimizing time, each and every time, saving the previous 'git pull origin master' updated artifacts, and preserving the 1TB files we copied to the container.
The ideal situation would be to have a container that is stateful, that spins down when not in use, and "spins up", or is made active for use when we need to do a build.
It would retain the previous git update (git pull origin master), and would retain all artifacts outside the git repo that we copy over. We also need shell access to the container (ssh, scp) etc.
A stateful 'Cloud Run' option would be ideal, but I don't know of such a thing (stateful containers with GCP that we can run and only be billed for runtime/compute time)
One solution is to use a VM for this. Add a startup script. In it
git pull origin master
Fire off the build as the next step in the script
Add this line which stop your compute
gcloud compute instances stop $(curl -H "Metadata-Flavor: Google" http://metadata.google.internal/computeMetadata/v1/instance/id) --zone=$(curl -H "Metadata-Flavor: Google" http://metadata.google.internal/compu
teMetadata/v1/instance/zone)
By the way, each time that you start your VM, it will apply the startup script and shutdown automatically. You keep your persistent disk, and thus your 1TB data, and you pay few because of automatic stop.
If you have to wait an external build. 2 solutions:
Either you set a sleep timer and shutdown after in the startup script
Or customize this tutorial -> At the end of your build, publish a message in PubSub, which trigger a function which will stop your instance.
EDITED to reply to comments
Here again, 2 solutions:
You can create a custom role with only the permission required. You can see all compute role here. If you provide an access to the console, I recommend list (to view the VMs), start and stop. Else, only start and/or stop if you write a script.
You can create a private function or Cloud Run. Assign a service account as identity to this, with enough role to start the VM (even if there is more permission as required -> it's not a good practice. Prefer the least privilege with custom role) and grant the role function.invoker or run.invoker to the user (depend if you use Function or Cloud Run) for allowing it to call this private endpoint and start the VM without right on the VM (only the right to perform an HTTP call).
My level of experience with the product is basic at best, but I'm expected to be a developer; I have a basic understanding of many things.
Right now my job is to investigate canceling lines in Purchase Orders. We have a workflow set up to handle those, and I'm trying to duplicate the scenario in my dev instance. Whenever a user cancels a line, the workflow is supposed to engage, and I've found that a batch job is what triggers that workflow to work (maybe that's the case with all workflows, but I don't know that for sure).
I've set up my personal Dev AX Instance under System Configuration => System => Server Configuration to use my personal Dev AOS server that my client is also running under, but when I go to System Configuration => Batch Jobs => Batch Jobs, then find the Batch Job I've been looking for and set the status to Waiting, the Batch Job never runs.
On our Test instance, the jobs is configured exactly the same way, except they use the AOS Server allotted for it.
I did a SQL script to change the batch job to use my personal Dev AOS Server, then did a restart of the Dynamics AX Servers.
There must be something I'm doing wrong for my personal dev instance. I've been reading some things from here about what may be going on and following down the list, but I'm pretty sure the problem is even stupider => https://www.daxrunbase.com/2017/07/02/troubleshooting-batch-jobs-in-ax/
First of all, do you have all 3 workflow jobs set up?
Workflow message processing
Workflow due date processing
Workflow line-item notifications
They can be set up from System administration > Setup > Workflow > Workflow infrastructure configuration.
Secondly, it is OK for the periodic batch jobs to have status Waiting. They will be in status Executing for a short time and then they will be Waiting for the next run. If the Scheduled start date/time value in this batch job is in the past, that could be a problem. Otherwise everything is OK.
Lastly, if you have already ticked the Is batch server check-box in System administration > Setup > System > Server configuration, please also make sure to move the workflow batch group in the Batch server groups section in the same form from Remaining groups to Selected groups.
The batch jobs should start at Scheduled start date/time - or a bit later, you'd need to wait a minute and refresh the grid.
Having a question on how the build queue is configured in CC.net.
I believe we have an issue , when trying to “force” build a scheduled project, the server tries to run several builds at the same time and fails
Most of them except the one that started first.
We need to get to a state when regardless how many builds are scheduled or how many we “force” start in about the same time, all build requests are placed in to a build queue and
executed one after finishing another in the order they were placed, and no extra request are generated.
Build Failed email is sent but the build was actually successful.
In short,The erroneous email is likely due to an error in the build server’s build scheduler/queue, trying to run 2 builds instead of one when asked for a “forced” build, as a result the first one is successful and the second one fails.
How to correct/resolve this issue....?
Thanks

To specify your projects' queue you need to set the queue property like this :
<project name="MyFirstProject" queue="Q1" queuePriority="1">
The default value is a queue per project. If you manually set the same queue (for example Q1) for all you project then, you will have a unique queue.
As for the queuePriority, the project (not yet started) in the queue are ordonned by queuePriority, low queuePriority projects start first.
It's all described in the cc net documentation which is now offline due to a problem at sourceforge.
