RedLin is founded and owned by Patrik Martinsson who has been in love with Red Hat for over a decade. We help our customers to automate, standardize and develop their infrastructure with the help of Linux and Red Hat products. At RedLin we can take on roles such as,

At RedLin we are used to tools such as Ansible and Puppet for automation and consistency. We also recognize the importance of having continuous deployment pipelines in place, not only for things like products and container images, but also for other parts of the infrastructure. Together with you, we want to build an fully automated, daily patched, high availability infrastructure.

We simply provide expertise and tailored solutions primarily built on Linux and Red Hat products.

My main responsibilities at The Swedish Employment Office has been to design, configure and install their new cloud container platform which is based on OpenShift 4.6. Ceph is used as the underlying storage and the Cisco ACI-CNI plugin for the network integration. I've put a lot of effort into self service and integrations to other parts of their infrastructure, such as Oauth2 authentication and project management through Servicenow. The cluster is installed on Cisco UCS hardware and spread over multiple datacenters for high availability.

I've also spend quite some time with development teams, helping them containerizing their applications. These applications has mostly been written in Java (Spring Boot / JBoss EAP), Angular, Python, NodeJS, etc. On top of that I've also been working with development teams helping them creating pipelines in Jenkins (Groovy) and automating their process for releasing new code.

In addition to that, I've also setup quite a few applications to demonstrate the power of a container platform, this includes applications such as PostgreSQL, MongoDB, Jira, Mattermost, Rocketchat, Element Matrix, Pastebins, etc.

My main responsibilities at TriOptima has been the installation, configuration and design of their Openstack and Ceph platform. The setup spans over three data centers and is based on Red Hat Openstack Platform 13 and Red Hat Ceph Storage 3. The design includes everything from different availability zones, storage pools (both local and stretched between multiple data centers), and involves roughly 50 nodes. The deployment of OpenStack is done through the Red Hat Director, while Ceph is being deployed using the Ceph Ansible Playbook. We have chosen this configuration to get an environment that scales and fulfills our internal customers requirements.

During the implementation I’ve encountered quite a few bugs in various components (neutron, octavia, heat-templates, networkmanager) which have actively been reported upstream (also monkey patched a few things locally to work around numerous deployment issues).

On top of that I’ve also built our own internal portal where the users can create, delete and manage access to their projects. Authentication to the portal, and to the cloud, is done via Kerberos (Active Directory) and supports Single Sign On.

My day to day-tasks consisted of managing Red Hat Enterprise Servers and Red Hat Enterprise Clients. Usually it involved making sure everything was up running and that the setups were consistent. This was essentially done by Puppet, Ansible and various automation-scripts (preferable in bash, perl or python).

I've been a key-player in SMHI's attempt to standardize their Linux Platforms (both for Servers and Clients). The goal was to make sure that every Linux Server and Client would be centrally managed and properly configured to SMHI's infrastructure and policies, that includes,

I've done a lot of scripting to various parts of the infrastructure, this includes Cisco UCS, VMware, Infoblox, HP iLO, Foreman, Puppet, ITRS OP5 Monitor, Cacti, Various CA technologies products, etc.
