Building rootless containers for JavaScript front ends

Building rootless containers for JavaScript front ends

jlord
By Joel Lord

By default, most containers are run as the root user. It is much easier to install dependencies, edit files, and run processes on restricted ports when they run as root. As is usually the case in computer science, though, simplicity comes at a cost. In this case, containers run as root are more vulnerable to malicious code and attacks. To avoid those potential security gaps, Red Hat OpenShift won’t let you run containers as a root user. This restriction adds a layer of security and isolates the containers.

Configuring NGINX for OAuth/OpenID Connect SSO with Keycloak/Red Hat SSO

Configuring NGINX for OAuth/OpenID Connect SSO with Keycloak/Red Hat SSO

sidde3
By Siddhartha De

In this article I cover configuring NGINX for OAuth-based Single Sign-On (SSO) using Keycloak/Red Hat SSO. This allows the use of OpenID Connect (OIDC) for federated identity. This configuration is helpful when NGINX is acting as a reverse-proxy server for a backend application server, for example, Tomcat or JBoss, where the authentication is to be performed by the web server.

In this setup, Keycloak will act as an authorization server in OAuth-based SSO and NGINX will be the relaying party.  We will be using lua-resty-openidc, which is a library for NGINX implementing the OpenID Connect relying party (RP) and/or the OAuth 2.0 resource server (RS) functionality.

I am pleased to announce the immediate availability of Red Hat Software Collections 3.0 Beta, Red Hat’s newest installment of open source development tools, dynamic languages, databases, and more. Delivered on a separate lifecycle from Red Hat Enterprise Linux with a more frequent release cadence, Red Hat Software Collections bridges development agility and production stability by helping you create modern applications that can be confidently deployed into production. Most of these components are also available in Linux container image format to streamline microservices development.

In addition to these new components having traditional support for x86_64, Red Hat Software Collection 3.0 Beta adds support for three new architectures: s390x, aarch64, and ppc64le.

NEW ADDITIONS to Red Hat Software Collections 3.0 Beta include:

Configuring NGINX to log HTTP POST data on Linux / RHEL

bshio
By Bachir Chihani

NGINX is a powerful web server that can easily handle high volumes of HTTP traffic. Each time NGINX handles a connection, a log entry is generated to store some information this connection like remote IP address, response size and status code, etc. The complete set of logged information with more details can be found here.

In some cases, you may be more interested in storing the body of requests, specifically POST requests. Lucky, the NGINX ecosystem is rich, and includes quite a few handy modules. One such module is the Echo module, which provides useful functionality for things like: echo, time, and sleep commands.

In our use case, to log a request body, what we need is to use the echo_read_request_body command and the $request_body variable (contains the request body of the Echo module). However, this module is not distributed with NGINX by default, and to be able to use it we have to build NGINX from its source code by building it with the source code of the Echo module included.

I’m very happy to announce that Docker images based on collections from Red Hat Software Collections (RHSCL) 2.0 are in beta testing.  The images are available from the Red Hat Container Registry, and we’ve got the set of collections for language, databases and web servers covered – a complete list is below.

If you’ve not tried out the Docker package from RHEL7 Extras, you need to enable the Extras channel, install the docker page, and start the docker service; an extended guide for RHEL Docker is available here.  Once you are set up, pulling the RHSCL Docker images is very simple… for example, you can fetch the Python 3.4 image as follows:
