By the end, the pipeline may produce some ‘artifact’. This could be the compiled software binary, X-as-Code State, or a log file. Google Cloud Build is a managed ‘serverless’ CI/CD pipeline service allowing you to run pipelines without the need to maintain any infrastructure and only pay for the compute over the time the pipeline is running.Kieran Goldsworthyfeatured imageGCPCI/CDMan Pageshttps://blog.kgol.xyz/en/posts/tgw-routing-domains/Wed, 30 Mar 2022 00:00:00 +0000Wed, 30 Mar 2022 00:00:00 +0000https://blog.kgol.xyz/en/posts/tgw-routing-domains/A more advanced routing architecture for AWS VPCs. TLDR: TGW can route traffic based on the source VPC as well as the destination IP. Before AWS introduced Transit Gateway, the only way to connect VPCs together was to use VPC peering. The main issue with this approach is that you need a VPC Peering between each pair of VPCs that you want to connect. To simplify large multi-VPC environments AWS released Transit Gateway, this allows for a hub-and-spoke model which allows for multiple VPCs to talk to each other with only a connection to a single hub.Kieran Goldsworthyfeatured imageAWSNetworkingMan Pageshttps://blog.kgol.xyz/en/posts/terragrunt-default-tags/Sat, 21 Aug 2021 00:00:00 +0000Sat, 21 Aug 2021 00:00:00 +0000https://blog.kgol.xyz/en/posts/terragrunt-default-tags/An approach to adding tags to all resources deployed by terragrunt This page describes a method to adding a set of default tags to all resources that can be tagged in an AWS account (other terraform providers may be compatible) More specifically, all resources deployed by terraform / terragrunt in a git repository. Setup First I should mention how I have set up the various terragrunt and terraform code, modules and repositories.Kieran Goldsworthyfeatured imageAWSTerraformTerragruntMan Pageshttps://blog.kgol.xyz/en/posts/aws-resource-policies/Sun, 27 Sep 2020 00:00:00 +0000Sun, 27 Sep 2020 00:00:00 +0000https://blog.kgol.xyz/en/posts/aws-resource-policies/The other side of AWS IAM Permissions IAM Policies This article will not be an in-depth look at IAM Policies, but it’s a good idea to go over the general basics. An IAM Policy is in the form of a JSON Object with the most important part being the statements. Each Policy Statement defines a set of actions, whether the action should be explicitly Allowed or Denied, and under which conditions the statement should apply.Kieran Goldsworthyfeatured imageAWSIAMSecurityMan Pageshttps://blog.kgol.xyz/en/posts/aws-iam-permissions-boundaries/Sat, 26 Sep 2020 00:00:00 +0000Sat, 26 Sep 2020 00:00:00 +0000https://blog.kgol.xyz/en/posts/aws-iam-permissions-boundaries/How to use this lesser known feature of AWS IAM A competent understanding of IAM Polices and how they affect the permissions of any User/Role they are attached to is important to understand Permission Boundaries. Introducing Permissions Boundaries Boundaries are applied to Users and Roles and they act as the upper-limit (like a Boundary… funny that) to the User/Role, regardless of what might be granted by the attached IAM Policies.Kieran Goldsworthyfeatured imageAWSIAMSecurityMan Pageshttps://blog.kgol.xyz/en/posts/installing-and-configuring-confluence-data-center-on-aws/Sun, 16 Feb 2020 00:00:00 +0000Sun, 16 Feb 2020 00:00:00 +0000https://blog.kgol.xyz/en/posts/installing-and-configuring-confluence-data-center-on-aws/Or at least how I did it Disclaimer This is my experience and steps I performed, YMMV.

If you are in business of building and configuring Linux servers, there will come a day where you need to configure a server with multiple Network Interface Cards and/or multiple IP Address. I had just such a task.
