Import Docker image

Say that you have followed the instructions in and now want to update a deployment configuration or a running pod so that it uses that image.

First list the image of intrest:

$ docker images
REPOSITORY                                                    TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
danbev/es                                                     latest              59d06a20aff1        17 hours ago        415.9 MB

First tag the image. Add the namespace/project name after the registry ip:port. For example, I'm going to add the image to the mbaas-logging namespace/project

Kibana, ELB and OpenShift V3

The openshift/origin-haproxy-router is an HAProxy router that is used as an external to internal interface to OpenShift services. When you create a route you specify the hostname and service that the route is connecting.

ProxyServlet setting cookies

The issue I'm seeing is that I'm not able to get the proxy to set a cookie, any cookie, but JSESSIONID in particular. The test I've run is with a target application that does basic authentication.

The client sends the credentials correctly and the users is logged in correctly, and I can see the following header from the backend:

JSESSIONID=v6OmD_TlluOcpSFr0GcpkqnR.dhcp-208-183; path=/backend-system-path

Since client only knows about the proxy, this will not be set by the browser. Instead we want something like ProxyPassReverseCookiePath, ProxyPassReverseDomain like mod_proxy.

Netty SockJS Refactoring

Netty SockJS Refactoring

Pull request #1615 is intended to add SockJS support to Netty. It does so by adding an API on top of Netty that end users have to implement. The interface that users had to implement looks like this:

 * Represents the server side business application server in SockJS.
public interface SockJsService {

     * The {@link SockJsConfig} for this service

SimplePush Server Performance

SimplePush Server performance

This doc intends to discuss preformance improvements for AeroGear SimplePush Server. Basically we are trying to figure out where we should focus to begin with.

This will start by picking an action that is performed by a client and profile for CPU perfomance, memory utilization and thread usage. After making improvements in that area, meansurement will be done again to see what the "hotspot" is after this.

This branch contains tests that can be run against an external server. Please see the "Integration Testing" section for details how to run the tests.


The SimplePush Server used in the Netty based implementation deployed to AS 7.1.1.Final.
