I have 2 home PCs with windows 10. I want to create test ipfs private network between 2 nodes.
I downloaded go-ipfs.
ipfs version 0.6.0
I executed
ipfs init
ipfs bootstrap rm --all
I made swarm.key and added node to config.
ipfs bootstrap add /ip4/62.122.132.55/tcp/4001/ipfs/QmYY9U3JFuMykjRjKd1jg6aPCmcf2UYpbaS8fHpwkAVvia
I checked if port 4001 is listening.
TCP [::]:4001 [::]:0 LISTENING
The same I made on the second node.
I started nodes
ipfs daemon
The result was
Initializing daemon...
go-ipfs version: 0.6.0
Repo version: 10
System version: amd64/windows
Golang version: go1.14.4
Swarm is limited to private network of peers with the swarm key

WebUI: http://127.0.0.1:5001/webui
Gateway (readonly) server listening on /ip4/127.0.0.1/tcp/8080
Daemon is ready
On second node I tried execute
c:\ipfs>ipfs swarm connect /ip4/62.122.132.55/tcp/4001/ipfs/QmYY9U3JFuMykjRjKd1jg6aPCmcf2UYpbaS8fHpwkAVvia

After some time daemon showed

What I missed?
can you run the following commands?
ipfs id
https://docs.ipfs.io/reference/cli/#ipfs-id
ipfs swarm peers
https://docs.ipfs.io/reference/cli/#ipfs-swarm-peers
ipfs boostrap list

I have private Azure Kubernetes cluster with installed Nginx Ingress (using internal Load Balancer)
This is non-production cluster and during weekends we plan stop it. But when we start it - it can't be finished successfully and after 30 minutes AKS cluster is in Failed state
After research I found that it happens only if Ingress is installed on private AKS with restricted outbound access
Any ideas how can it be solved?
one thing you can do is upgrade your Kubernetes cluster:
Check the upgrades available for your cluster
az aks get-upgrades --resource-group <resoure-group-name> --name <cluster-name> --output table
Then upgrade your cluster
az aks upgrade \
--resource-group <resoure-group-name> \
--name <cluster-name> \
--kubernetes-version <kubernetes_verion>
Replace the Kubernetes version by a version you got from the first command
I've a docker installed in a VM in VirtualBox and I'm attempting to run a container with a dot Net Core application that connects to a MySQL database on the hosts machine. So I've configured the forwarding port for both mysql and my application on Virtual Box. I'm able to access my service through "http://localhost:3131/api/users/login" in the host machine but it throws an error saying that couldn't connect with the MySQL data base. I'm also able to run the app in the host machine when I'm not using docker. I've looked in other threads on the internet but nothing that enlightened me exactly except the last command shown below but I can't run since the MySQL authentication are configured is hard coded in the application not with a config file. The general configuration is as follows:
Program.cs
var host = new WebHostBuilder()
.UseKestrel()
.UseContentRoot(Directory.GetCurrentDirectory())
.UseIISIntegration()
.UseStartup<Startup>()
.UseApplicationInsights()
.UseUrls("http://*:80")
.Build();
Dockerfile

localhost (that I thought it would appear the port 3131, but it calls the service anyway.)

Since you're running inside VirtualBox, there's another layer between the VirtualBox host machine and docker. You have a machine hosting VirtualBox (1) -> Linux in VirtualBox (2) -> docker (3).
"localhost" for docker (3) means (2) so it expects mysql to be on (2). In your case, you have mysql on (1).
The only way to access (1) from (3) is by explicitly using the IP of (1) and not the "localhost" alias.
I have been trying Windows Containers on windows server 2016 TP5. Suddenly I started getting error while running a container with port maping option -p 80:80
c:\>docker run -it -p 80:80 microsoft/iis cmd
docker: Error response from daemon: failed to create endpoint sharp_brahmagupta on network nat: HNS failed with error : Failed to create endpoint.
I made sure that no other container is running and port 80 on host machine is not being used by any other service.
Did anyone face same issue?
After searching around I stunbled upon this issue on github. This seemed to be a known issue with Windows containers on Windows server TP5.
Then thanks to this forum, I found the solution
You can check active static port mapping with below command
C:\>powershell
PS C:\>Get-NetNatStaticMapping
StaticMappingID : 3
NatName : Hda6caca4-06ec-4251-8a98-1fe0b4c5af88
Protocol : TCP
RemoteExternalIPAddressPrefix : 0.0.0.0/0
ExternalIPAddress : 0.0.0.0
ExternalPort : 80
InternalIPAddress : 172.31.181.4
InternalPort : 80
InternalRoutingDomainId : {00000000-0000-0000-0000-000000000000}
Active : True
From above output it seemed that even though container was removed the static port mapping was not removed and was still active.
But I removed it with below command.
PS C:\> Get-NetNatStaticMapping | ? ExternalPort -eq 80 | Remove-NetNatStaticMapping
Then simply rebooted the system and the error was gone.
For me these steps solved the problem:
Stop-Service docker
Get-ContainerNetwork | Remove-ContainerNetwork
Get-NetNat | Remove-NetNat
Get-VMSwitch | Remove-VMSwitch
Start-Service docker
(suggested by JMesser81 at:https://github.com/Microsoft/Virtualization-Documentation/issues/273)
I had similar error.
$ docker --version
Docker version 1.13.0-rc3, build 4d92237
$ docker-compose -f .\docker-compose.windows.yml up
Starting musicstore_db_1
ERROR: for db Cannot start service db: {"message":"failed to create endpoint musicstore_db_1 on network nat: HNS failed with error : Unspecified error"}
ERROR: Encountered errors while bringing up the project.
Static mapping removal did not work, only network removal helped:
Get-ContainerNetwork -Name nat | Remove-ContainerNetwork
Execute the command in PowerShell as administrator, then restart Docker.
Update:
Use CleanupContainerHostNetworking.ps1 script to resolve Docker 17 networking issues.
.\CleanupContainerHostNetworking.ps1 -Cleanup -ForceDeleteAllSwitches
I had a docker and docker-compose which were already working on Centos.
I did the following changes to make it work on windows server 2016:
Stop the docker service, remove nat, start the docker service.
ps>stop-service docker
ps>Get-ContainerNetwork | Remove-ContainerNetwork -Force -ea SilentlyContinue
ps>start-service docker
Configure network in your docker-compose.yml
version: '3.7'
networks:
default:
external:
name: nat
That's It!
I have Wildfly 10 running on Openshift Origin 3 in AWS with an elastic ip.
I setup a Route in Openshift to map / to the wildfly service. This is working fine. If I go to http://my.ip.address I get the WildFly welcome page.
But if I map a different path, say /wf01, it doesn't work. I get a 404 Not Found error.
My guess is the router is passing along the /wf01 to the service? If that's the case, can I stop it from doing it? Otherwise how can I map http://my.ip.address/wf01 to my wildfly service?
I also want the wildfly console to be accessible from outside (this is a demo server for my own use). I added "-bmanagement","0.0.0.0" to the deploymentconfig but looking at the wildfly logs it is still binding to 127.0.0.1:
02:55:41,483 INFO [org.jboss.as] (Controller Boot Thread) WFLYSRV0051:
Admin console listening on http://127.0.0.1:9990
A router today cannot remap/rewrite the incoming HTTP path to another path value before passing it along. A workaround is to mount another route+service at the root that handles the root and redirects / forwards.
You can also use port-forward :
oc port-forward -h
Forward 1 or more local ports to a pod
Usage:
oc port-forward POD [LOCAL_PORT:]REMOTE_PORT [...[LOCAL_PORT_N:]REMOTE_PORT_N] [options]
Examples:
# Listens on ports 5000 and 6000 locally, forwarding data to/from ports 5000 and 6000 in the pod
$ oc port-forward -p mypod 5000 6000
# Listens on port 8888 locally, forwarding to 5000 in the pod
$ oc port-forward -p mypod 8888:5000
# Listens on a random port locally, forwarding to 5000 in the pod
$ oc port-forward -p mypod :5000
# Listens on a random port locally, forwarding to 5000 in the pod
$ oc port-forward -p mypod 0:5000
I used docker-machine with Azure as the driver to spin up a VM. I then deployed a simple nginx test container on to the host. My issue is that when I try to set and endpoint I am getting the following error:
azure vm endpoint create huldra 80 32769
info: Executing command vm endpoint create
+ Getting virtual machines
+ Reading network configuration
+ Updating network configuration
error: Parameter 'ConsoleScreenshotBlobUri' should not be set.
info: Error information has been recorded to /Users/ryan/.azure/azure.err
error: vm endpoint create command failed
When I look at the error log it pretty much repeats what the console said Parameter 'ConsoleScreenshotBlobUri' should not be set.
