Map Subdomains to Docker Containers with Synology

The other day I got fed up with having to insert diskstation.local:12345 to point towards an installed service on my NAS. I also thought that my SO has difficulties remembering all the ports (I do too) and cleaning up the browser cache doesn’t help either. So, I thought: Wouldn’t it be nicer if instead of […]

List Rundeck Jobs for a Project

Now that we Rundeck have a list of project names, we might want to see which jobs were created for each project. To do this, we need: The Rundeck instance’s address (server, port) The API key (api_key) A project’s name (project_name) First, we need to get the list of jobs for a project:

The […]

List Rundeck Projects

The other day I found out that Rundeck has an API which allows it to be controlled remotely by scripts. I’ve decided to write a script to list all the projects defined in a rundeck instance. Prerequisites Before you start, you need: The instance’s URL (server and port) An api key for the user Make […]

Remove Large Files in Git

TL;DR: BFG is your friend. java -jar bfg.jar -b 50M myrepo-bfg.git for example The other day I’ve committed a rather large file by mistake (generated movie of the git commit history). This was a bit annoying because all other developers would have suddenly to check out a 1G file :( with no LFS support… As […]

Fix 418 Unused Error on Dreamhost

TL;DR: Have a look at the error log and then to the violated rule. Suddenly, I started to get 418 errors on one of my sites. I’d just get 418 from the source and as they say: that was that. Normally, I don’t even notice such errors, but this one broke a bunch of pages. […]

Run a Rundeck Command as a Different User

TL;DR: Add the rundeck user to the sudoers and then use sudo Installing rundeck on Ubuntu usually results in creating a rundeck user. We had a bunch of issues creating a rundeck job because we needed to execute a command as a specific user (only that user had access to some resources). Unfortunately, rundeck is […]

Fix Not Found Package Errors with .staging Warnings on Npm Install

TL;DR: Clean the npm cache and the package-lock.json The other day I started to get ENOENT warning when running npm install like:

only to have the compilation failing with something like:

I’ve looked into it and the conclusion was that the error occurred because I’ve updated my node/npm version. Most answers recommend removing […]

Fix TS1144 for e.g. flex-layout

TL;DR: Update your typescript version dependency. These days we’re updating some angular apps to the most recent version (6 at the time of writing this entry). Everything is nice, with the exception of various errors we get because of the other dependencies. The most recent one was a TS1144: ‘{‘ or ‘;’ expected in one […]

Build a Django Docker Image with Cx-Oracle

TL;DR: Don’t use alpine images. There’s a glibc issue. We added a cx-oracle dependency to one of our django apps. As the previous image was just an alpine basic (python) image we needed to put in place a process to build the new image. Initially, I’ve tried to use the same alpine image (oh, the […]

Execute a Command in Every Directory with Bash

TL;DR: Use a find-based loop The other day I was wondering how to execute a command in each sub-directory of a project. In python, you have os.walk. In C, I would’ve probably written myself something just for fun etc. In shell, I know you have find which is capable of finding all directories (find (dir) […]
