Is there is any other way to access environment variable in jenkinsfile?
I am using
env.envvar0
or
def pass='${envvar0}'
Can i access env['envvar'] , why i am asking i want envvar i can use as.
varvalue='envvar'+'0'
print env[varvalue]

I am having a hard time finding a way where I can store some global variable on the Jenkins server and then keep updating it through the jobs. My use case is whenever there is any new build available, it triggers downstream jobs. Also, there are some jobs that run periodically in a week. I want to store the latest build number on the server so that whenever the periodic job runs, it runs on the latest build.
I have tried saving global variable but I can change it within a job using envInject but that change is not reflected globally.
One option for storing parameters on the server scope is using the Global Environment Variables.
They are available via: Manage Jenkins -> Configure System -> Global properties -> Environment variables.
These parameters are available for all jobs and can store parameters in a 'server wide' scope that will then be available everywhere.
You can then update or set them via code using the following groovy method:
#NonCPS
def updateGlobalEnvVariable(String name, String value) {
def globalNodeProperties = Jenkins.getInstance().getGlobalNodeProperties()
def envVarsNodePropertyList = globalNodeProperties.getAll(hudson.slaves.EnvironmentVariablesNodeProperty.class)
if (envVarsNodePropertyList == null || envVarsNodePropertyList.size() == 0) {
def envVarsNodePropertyClass = this.class.classLoader.loadClass('hudson.slaves.EnvironmentVariablesNodeProperty')
globalNodeProperties.add(envVarsNodePropertyClass.newInstance())
}
envVarsNodePropertyList.get(0).getEnvVars().put(name, value)
}
This function should better be placed in a Shared Library from which it can be called by every job that needs to update the Global parameters.
You might be looking for https://plugins.jenkins.io/envinject/ plugin which does exactly what you're looking for.

the question is very simple:
How do I create a conditional breakpoint in byebug about a variable assignment? This is more an event than a condition. But how would you proceed if you do not know where in the code the assignment could happen?
Watching a variable in step by step manner isn't forthbringing. I would need to watch it, until some arbitrary value is assigned to the identifier.
I only know that an Identifier is somewhere in the Rails program, maybe even in the initialization process, is assigned a value to. I don't know when or what. The "what" is what I want to find out. Do you think there is a debugging solution?
Thanks

E.g. if you know that the variable starts off as nil
byebug unless x.nil?
Then scatter that statement around your code wherever that variable is in scope and you suspect it may be changed. Or if you want to restrict it to a certain operation or loop, set a global variable where you want to start looking like
$enable_byebug = true if name == 'foo'
do(something)
...
byebug if !x.nil? && $enable_byebug
This is one of the few contexts where I'm happy to use global variables.
I'm trying to add a log group subscription to an existing lambda.
(cont, log_group) = self.container_for_ecr_image(build_stack.task_repo, task, 'task1')
log_group.add_subscription_filter(id="task1-subscribe", destination=??, filter_pattern="")
I have the function 'ARN' and name but no reference to the function.
How can I extract the function reference using CDK if I only have the function ARN?
Thanks
The way to do it is:
aws_lambda.Function.from_function_arn(self, id="id", function_arn="function_arn")
I could be wrong here - but from looking at the docs it looks like the Alias class from Lambda might be able to "create" a reference to an existing lambda. But I'm not too sure as I'm quite new to this stuff.
It's difficult to work with existing stuff in the CDK because I think the best practice is to create everything through CloudFormation (if IaC is your goal)
Let's say that at the beginning of the run I set a variable in the session like this:
session[:plan_id]= "plan_id_number_in_string"
later in the run I want to ovewrite that value, meaning:
session[:plan_id]= "plan_id_2_number_in_string"
I'm having issues with this, can this be done?
Right now I have a container for an API that I am looking to push to an AWS Fargate instance that has a connection string for a DB on a privately hosted server. For testing this has been stored in a string in my Golang program, but I don't really want to push that even with the program already compiled.
I have looked into using the GO AWS SDK for the SecretsManager, but I am not sure if that is the best way to go, or if it will even work like I am hoping it will. What is the best way to handle this?
Hardcoding things into the program is obviously never the best choice, so I share your pain and the need for something better, that could be:
Define the connection string into an environment variable. This solution does not keep the information "secret", so if it's something that you would not like to have it readable in any way, try with the next
Define the connection string into Secrets Manager and refer to in the environment variable definition
Doing this with CloudFormation we will have in the first case:
...
Environment:
-
Name: CONNECTION_STRING
Value: 'YOUR VALUE'
...
While in the second case we would have:
...
Environment:
-
Name: CONNECTION_STRING
Value: '{{resolve:secretsmanager:MySecret:SecretString:connection_string}}'
...
