Delete Executions in Rundeck – Wrapping it all Up

Posted by in IT, Software, Tutorial

The previous posts have built the components to allow us to get projects, jobs, executions and remove executions from a Rundeck instance via its API. Now, we can just wrap them up :) The list of packages we need is:

For convenience, I’ve declared a bunch of constants we can use throughout the project:

As we already have all the helper functions defined, we only need to wrap them in a convenient execution command:

The logis is fairly simple: Get the list of projects For each project,…read more

List Rundeck Jobs for a Project

Posted by in IT, Software, Tutorial

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 result is also an XML, just like the one for the projects. Therefore, we need to parse it:

At the end of this exercise, we’ll have a list of job names (IDs). HTH, A…read more

List Rundeck Projects

Posted by in IT, Software, Tutorial

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 sure the user has enough credentials to list the projects The code I’ve picked up Python as language for the task just because I’m more familiar with it in this context. Therefore, another dependency is…read more

Remove Large Files in Git

Posted by in Software, Tutorial

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 I took the opportunity to clean up the repository also, I’ve noticed the size of the cloned reop was rather huge! So, I was presented with several options Create a new repo with the cleaned…read more

Run a Rundeck Command as a Different User

Posted by in Software, Tutorial

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 not as versatile as Jenkins (plugins and such) — or I couldn’t find anything relevant at the time. Initially, I’ve tried adding the rundeck user to the same group as the other user, but only…read more

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

Posted by in Software

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 the npm cache either via rm -rf or via npm cache clean. however, this didn’t fix my problem. This issue seemed to match my behavious and one of the solutions was to remove package-lock.json and…read more

Fix TS1144 for e.g. flex-layout

Posted by in Software

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 of the dependencies (flex-layout to be precise). As it’s a popular 3rd party library, it’s more probable the error occurs because of something on our side than on theirs. So… Since it’s a TS error,…read more

Build a Django Docker Image with Cx-Oracle

Posted by in Software, Tutorial

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 slimmed down size is sooo tempting), but then I’ve hit a bunch of “Unknown symbol” messages when I’ve ran the install of cx-oracle in the docker build process. Subsequently, I’ve had to switch to python:3.6-slim-jessie….read more

Execute a Command in Every Directory with Bash

Posted by in Software, Tutorial

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) -type d). All I need to do is to wrap this in a loop and for this one has two options: Commmand line style

or

Script style with a loop

The choice…read more

Build Update Statements with Oracle SQL Developer and Python

Posted by in Software, Tutorial

By default, SQL Developer can only export INSERT statements. This is quite unfortunate when one needs to build UPDATE statements because their syntax is different. I’ve tried to use regexp to convert the statements but I didn’t find it not straight forward at all. So, I cam up with the following strategy: Export the data as JSON Use a python script (below) to write the statements The python script We first need to specify things like the DB Schema, table and the primary key:

Subsequently, I’ve defined a wrapper…read more
