Is it possible to scope Openstack CLI output for listing networks only for a single project. I have tried multiple options like --os-project-id, --os-project-name etc but it seems to list down all networks across multiple projects/tenants.
Currently, the command I am using is:
openstack network list --os-username XXX --os-password YYY --os-project-id ZZZ
Note: The credentials that I am using here are of an 'admin' account
Parameters set in the environment are :
OS_PROJECT_ID=XXX
OS_REGION_NAME=XXX
OS_TENANT_ID=XXX
OS_USER_DOMAIN_NAME=XXX
OS_PROJECT_NAME=XXX
OS_AUTH_VERSION=XXX
OS_IDENTITY_API_VERSION=XXX
OS_PASSWORD=XXX
OS_AUTH_URL=XXX
OS_USERNAME=XXX
OS_TENANT_NAME=XXX
OS_INTERFACE=XXX
OS_PROJECT_DOMAIN_NAME=XXX
May be your networks are shared by all tenants. If you only have a few networks you can verify with neutron net-show Network-Name and review the shared attribute
BTW I use the env variable OS_PROJECT_NAME to switch between projects
Without any explicit filter specified in the parameters, Neutron's network API returns all networks that the user accessing the API has privileges to list. The recommended way to scope down the list of networks to a specific project is to explicitly specify that filter.
Via CLI, you can scope the list to a specific project "demo" using the following example:
openstack network list --project demo
You can see more filtering options via the help text:
openstack help network list
Issues were caused by an older version of Openstack CLI v3.7.0
Using Openstack CLI version v3.13.0, I was able to solve my requirement. By default, with the domain admin account, the CLI still dumped the entire network list but with the --long flag, the 'project' field this time was populated and I could filter out the results for the specific project.
This was not the case with the previous CLI versions. Usage of '--long' flag had all the values of 'Project' as none.

Openstacks configuration page says (highlights and numbering by me):
OpenStackClient looks for a file called clouds.yaml in the following locations: I) current directory II) ~/.config/openstack III) /etc/openstack
but when I place an openstack clouds.yaml at I-III), it doesn't read any data from it. openstack configuration show at least is not showing the additional information and calls that would require said information fail due to that information not being available to openstack.
I used the command: openstack configuration show
openstack configuration show won't show any information from your clouds.yaml unless you either specify --os-cloud <name> on the command line or set the OS_CLOUD environment variable (because otherwise how does it know which cloud configuration to use?).
My apps using bonjour service to conversation with each other via local network.
I am facing a problem on Xcode12 with OS14 device.
A device publish a service with server type name depends on self device IP address
(example: 192.168.33.20 -> _1921683320._tcp)
B device searching a service with service type depends on A device IP address
(example: _1921683320._tcp)
According to apple document..From OS14~
https://developer.apple.com/documentation/multipeerconnectivity
Important
Apps that use the local network must provide a usage string in their Info.plist with the key NSLocalNetworkUsageDescription. Apps that use Bonjour must also declare the services they browse, using the NSBonjourServices key.
because my service type name is named by local network ip, it is changeable base on local network setting, so I am thinking about to using wildcard to define the service type name.
example: _*._tcp
but seems wildcard is not available on this definition.(I tried it)
I am also thinking about changing the naming method on A device
(example: 192.168.33.20 -> _20._tcp)
and add _1.tcp ~ _255.tcp to info-plist
But if I changed the naming method, B device could not find A device until version up.
Any idea for this problem? Please help.
I'm currently working through the same issue - Bonjour service name is dynamically created based off the iPad name to form a local mesh network. The conclusion that I have came to is com.apple.developer.networking.multicast is required for this to function without completely overhauling how all that logic is done. (More info here)
You will have to request permission from apple by filling out a form here. Let me know if this works for you!
The thing I am finding is, you "might" not be able to use a wildcard, but you can put multiple entries in the plist:
Item 0 _multicastapp0-p._tcp
Item 1 _multicastapp1-p._tcp
Item 2 _multicastapp2-p._tcp
Item 3 _multicastapp3-p._tcp
etc
Item N _multicastappN-p._tcp
So for some reason if you are trying to have multiple "Groups" of 8 or have a device have it's own "collection" i.e. be a server and have 3 devices connect to that, you can.
I haven't "fully" tested but I am going to be doing this in my apps, I did test using multiple keys tho, but not fully, no errors...
I've been trying to provision a 2-node-type service fabric cluster using ARM. The secondary node type (backend) should not be exposed to the internet. For that I've created a loadbalancer with an internal IP-Address.
Everything gets provisioned correctly but I cannot get the nodes added to the cluster. From the Azure portal when I open the cluster it says it has no nodes in it even though it has the node types configured.
I have even tried downloading the template produced by the azure portal after creating a service fabric cluster. I have also executed one of the templates provided on github and I cannot still see any nodes in the cluster.
Any suggestion what I could be missing?
Thanks
Glad to hear you got that sorted. Regarding your follow-up question on deploying to the backend node-types, that's where you'd use placement constraints. When you create clusters in Azure through ARM, it automatically sets up a placement property on each node using the node type name you defined. So on your back-end nodes, assuming your node type is called "backendnode" you'll have the following placement policy defined:
NodeTypeName: backendnode
When you deploy your services, just use that as your placement constraint:
New-ServiceFabricService -ApplicationName "fabric:/myapp" -ServiceName "fabric:/myapp/myservice" -ServiceTypeName "myservicetype" -Stateful -MinReplicaSetSize 2 -TargetReplicaSetSize 3 -PartitionSchemeSingleton -PlacementConstraint "NodeTypeName == backendnode"
My original problem was that I want to increase my DynamoDB write throughput before I run the pipeline, and then decrease it when I'm done uploading (doing it max once a day, so I'm fine with the decreasing limitations).
They only way I found to do it is through a shell script that will issue the API commands to alter the throughput. How does it work with my AMI access_key and secret_key when it's a resource that pipeline creates for me? (I can't log in to set the ~/.aws/config file and don't really want to create an AMI just for this).
Should I write the script in bash? can I use ruby/python AWS SDK packages for example? (I prefer the latter..)
How do I pass my credentials to the script? do I have runtime variables (like #startedDate) that I can pass as arguments to the activity with my key and secret? Do I have any other way to authenticate with either the commandline tools or the SDK package?
If there is another way to solve my original problem - please let me know. I've only got to the ShellActivity solution because I couldn't find anything else in documentations/forums.
Thanks!
OK. found it - http://docs.aws.amazon.com/datapipeline/latest/DeveloperGuide/dp-concepts-roles.html
The resourceRole in the default object in your pipeline will be the one assigned to resources (Ec2Resource) that are created as a part of the pipeline activation.
The default one in configured to have all your permissions and AWS commandline and SDK packages are automatically looking for those credentials so no need to update ~/.aws/config of pass credentials manually.
I am using .NET SDK for AWS and and trying to create a service that can create/mange instances. As part of this I want to create an EC2 instance in a specific VPC (non-default). There may have more then one VPC in a zone and I want to programatically be able to create/manage instances in any of the VPC rather than just the default VPC.
Is this possible? If yes how? I looked through the API docs and could not find a way to specify the VPC at the time of creation of EC2 isntance.
The VPC appears to be implied by the subnet-id that you specify. If this doesn't get you there, it might at least get you an error message explaining what you've missed.

http://docs.aws.amazon.com/AWSSdkDocsNET/latest/DeveloperGuide/run-instance.html
From the underlying REST API:
SubnetId
[EC2-VPC] The ID of the subnet to launch the instance into.
Type: String
Default: None
Required: No
