Merge global and environment variables - capistrano

I need to link specific file in production environment in addition to global linked_files:
My current configs:
deploy.rb
set :linked_files, ['config/database.yml']
production.rb
set :linked_files, ['config/database.yml', 'config/email.yml']
Is it possible to add some files in production.rb to linked_files from deploy.rb?
Like this:
production.rb
set :linked_files, merge('config/email.yml')


It's quite old, but just for the sake of knowledge:
set :linked_files, fetch(:linked_files) | %w{config/unicorn/test.rb }
In other words, simply join arrays from global and environment file

How can I define env variable value during the release phase in Azure?

I have an Nx monorepo project set up. I want to set some environment variables to use throughout my app. I'm looking for a solution where I can define a value for these variables during the release process to each environment (QA, Test, Dev).
Example:
NX_API_URL is my environment variable in my .env file.
If I release to QA env the variable should be NX_API_URL=api-url-qa.com.
If I release to Test env the variable should be NX_API_URL=api-url-test.com
I have found solutions during the build process but that's not going to work, it needs to be at the release phase. How can I accomplish this?

If the file that you'd like to modify during the deployment process is either XML or JSON you can define the URLs as tokens and use standard 'FileTransform' task to replace them: https://learn.microsoft.com/en-us/azure/devops/pipelines/tasks/reference/file-transform-v2?view=azure-pipelines
For more details regarding file transformation please refer to documentation: https://learn.microsoft.com/en-us/azure/devops/pipelines/tasks/transforms-variable-substitution?view=azure-devops&tabs=Classic
If none of the links above will help you with this, then I'd suggest to create PS script to do whatever modifications are required, like adding a line after specific line definition: https://social.technet.microsoft.com/Forums/office/en-US/fabc9790-0ffe-43b2-9d6b-bc483cd28bb6/add-line-to-a-text-file-just-after-a-specific-line-with-powershell?forum=winserverpowershell

set project wide variable in rundeck to use in jobs

is it possible to set sort of a project-variable in rundeck?
I am organizing jobs in projects, but the jobs are mostly the same and use the same values over and over again. If I could set variables per project, I could just copy jobs from project to project without having to adapt the same parameters over and over again...
like... path=/path/to/project
and use the variable path in jobs
Thanks, regards
Jochen

You can define a global variable for that. You can define it on framework.properties file like framework.globals.myvar=myvalue or at project level (project.properties config) like project.globals.myvar=myvalue, to access it just use ${globals.myvar} for steps, #globals.myvar# for inline-scripts or $RD_GLOBALS_MYVAR for scripts.
UPDATE:
In Rundeck 3.1/3.2/3.3/4.X the "project.properties" isn't a "file", is a config reachable/editable following this.

Environment variables for Rundeck groups in a project

Is there a way to create global environment variables for groups in Rundeck in the same way we can create one for Projects.
For eg : project.globals.version = 123

You can create a "really globally" variables from framework.properties file using framework.global.myvar=myvalue and from project.properties file using project.globals.myvar=another_value (for each project).
You've more info here.

Capistrano - How to put files in the shared folder?

I am new to Capistranoand I saw there is shared folder and also option :linked_files. I think shared folder is used to keep files between releases. But my question is, how do files end up being in the shared folder?
Also, if I want to symlink another directory to the current directory e.g. static folder at some path, how do I put it at the linked_dirs ?
Lastly how to set chmod 755 to linked_files and linked_dirs.
Thank you.

Folders inside your app are symlinks to folders in the shared directory. If your app writes to log/production.log, it will actually write to ../shared/log/production.log. That's how the files end up being in the shared folder.
You can see how this works by looking at the feature specs or tests in Capistrano.
If you want to chmod these shared files, you can just do it once directly over ssh since they won't ever be modified by Capistrano after they've been created.
To add a linked directory, in your deploy.rb:
set :linked_dirs, %w{bin log tmp/backup tmp/pids tmp/cache tmp/sockets vendor/bundle}
or
set :linked_dirs, fetch(:linked_dirs) + %w{public/system}

Capistrano 3.5+
Capistrano 3.5 introduced append for array fields. From the official docs, you should use these:
For Shared Files:
append :linked_files, %w{config/database.yml}
For Shared Directories:
append :linked_dirs, %w{bin log public/uploads vendor/bundle}

I've written a task for Capistrano 3 to upload your config files to the shared folder of each of your servers, it'll check these directories in order:
config/deploy/config/:stage/*.yml
config/deploy/config/*.yml
And upload all config files found. It'll only upload the files if they've changed. Note also that if you have the same file on both directories then the second one will be ignored.
Here's the code: https://gist.github.com/Jesus/448d618c83fb0445ebbf
One last thing, this task is just uploading the config. files to your remote shared folder, you still need to set linked_files in config/deploy.rb, eg:
set :linked_files, %w{config/database.yml config/aws.yml}
UPDATE:
If you're using Git, you'll probably want to ignore these files:
echo "config/deploy/config/*" >> .gitignore

There are 3 simple steps you can follow to put a file that you don't want to change in consecutive releases; add your file to linked_files list.
set :linked_files, fetch(:linked_files, []).push('config.php')
Select all the files that you want to share. Put this file from your local to remote server through scp
scp config.php deployer#amazon:~/capistrano/shared/config.php
Now, deploy through the command given below:
bundle exec cap staging deploy
of course, staging can be changed as per requirements may be production,sandbox etc.
One more thing, because you don't want your team members to commit such files. So, put this file to your .gitignore file. And push it to git remote repo.

For Capistrano 3.5+, as specified in official doc :
append :linked_dirs, ".bundle", "tmp"

For me non of the above worked so I ended up adding two functions to the end of the deployment process:
namespace :your_company do
desc "remove index.php"
task :rm_files do
on roles(:all) do
execute "rm -rf #{release_path}/index.php"
end
end
end
namespace :your_company do
desc "add symlink to index.php"
task :add_files do
on roles(:all) do
execute "ln -sf #{shared_path }/index.php #{release_path}/index.php"
end
end
end
after "deploy:finished", "your_company:rm_files"
after "deploy:finished", "your_company:add_files"

Cloudbees Jenkins Folders Plugin: Folder Name as Enviroment Variable

Is the Folder Name available as an environment variable similar to JOB_NAME?
For a folder; JOB_NAME contains the full path including parent folders. I want the immediate parent folder as an environment variable.

I used:
FOLDER_NAME=${JOB_NAME%/*}
STAGE=${JOB_NAME##*/}
See http://www.tldp.org/LDP/abs/html/parameter-substitution.html

No such variable exists, but $(basename $(dirname $JOB_NAME)) would give you what you are asking for.

Using the suggestion of $(basename $(dirname $JOB_NAME)) combined with the Environment Script Plugin, you should be able to set such an environment variable by selecting Generate environment variables from script and then providing the Script Content of:
echo FOLDER_NAME=$(basename $(dirname $JOB_NAME))
