I believe the production architecture guide do tell you how each nic is used

2017-08-20 19:41:22 -0500 answered a question How to setup docker insecure registry for kolla?

Hi EchoGhost,

If you are using a newer version of docker. docker daemon command is no longer working. You should change ExecStart from ExecStart=/usr/bin/docker daemon $INSECURE_REGISTRY to ExecStart=/usr/bin/docked $INSECURE_REGISTRY

Hope this help.

2017-04-03 00:14:52 -0500 answered a question can not access floating ip

Hi, I would like to ask have you modified the security group for instances. By default, both ssh (TCP port 22) and ICMP (ping) connections are not allowed.

You can refer to documentation here for how to create and modify security groups.

Check your internet connection. It seems that it's downloading cirros image. However it shouldn't take so long as it's small.

Did you edit security groups for the instance to allow ssh (TCP port 22) connections?

Can you add more details about how you created the keys on Mac and how to you try to ssh your instance?

Remember to check security group rules that port 22 and ICMP is open before ssh or ping the server.

I am getting un-authorized error when i try to access a container in swift, though I have set the permission to reaad-only (I used Kolla all in one):

*~$ wget
--2017-01-12 13:11:42--
Connecting to connected.
HTTP request sent, awaiting response... 401 Unauthorized

I already set the permission using the following command:

**swift post -r ".r:*" admin**

~$ swift stat admin

I don't think it's possible without external network.

2016-08-11 03:39:34 -0500 edited question keypair management best practices

Dear All,

I am trying to understand - what may be best practices for managing Keypairs for an instance. Typically let's say we have a dozen instances all of them can potentially share a keypair. Basically for a third-party software like guacamole - to be able to access the private key what are recommended choices? Basically, all of this is to be done automatically through some orchestration code with no user intervention. For instance, some choices that come to mind include -

  1. Basically save the private key securely in Swift Object storage (but in a deployment, just deploying 'swift' object store just for storing key-pairs is certainly an overkill).
  2. Write a simple application where the orchestration code stores the keypairs (that runs on say guacamole server) and then use those (this way 1. is avoided - but new code - and it's baggage).

Any inputs including pointers to existing code are greatly appreciated.

Got this problem too on a DL360p gen8 Server. I've configured the base system to install on a SD card. Still not able to resolve the problem through this thread.
