I am working on a Django project, I have integrated it withJenkins Multibranch Pipeline. I cannot inject environment variables by the Multibrach Pipeline option even after installing the Environment Injector plugin.
I have evironment variables like DB_PASSWORD that must be included in the envvars.
Any insight will be highly appreciated.
Since you require secrets, the best practice way is to use the withCredentials plugin which can load credentials stored in Jenkins credential store and expose them as ENV variables to code executed within its block/closure. Using withCredentials does not expose them in Jenkins logs
withCredentials([[$class: 'UsernamePasswordMultiBinding',
credentialsId: 'DB_Creds',
usernameVariable: 'DB_USERNAME',
passwordVariable: 'DB_PASSWORD']]) {// do stuff }
For non sensitive Env vars use withEnv
withEnv(["AWS_REGION=${params.AWS_REGION}"]) {// do stuff }
If for whatever reason you want Env vars set across your entire pipeline (not entirely recommended but sometimes necessary):
env.MY_VAR='var'
echo("My Env var = ${env.MY_VAR}")

I'm new to AWS and DevOps. But still experimenting here on our project, and I saw this environment variables section in CodeBuild, and I was trying to console.log the ENVIRONMENT which is sgdev1, but I'm getting undefined, when I check on CloudWatch.
I console log it like this, since I saw in our codebase it's written like that to access the environment variables. Though in this way, I'm only sure that it fetches those variables stored in my local machine, in the environment variables in Windows OS.
console.log(process.env.ENVIRONMENT)
Also I'm not that really sure where to put the environment variables, I'm quite confused since we also uses was secrets manager which holds some of our variables, then there's this codebuild env variables. I'm confused where should the variable that identify if the server is a dev site or production, but anyways the original question is how can I read these variables from codebuild environment variables? Forgive me if something stupid is going on with my question.
I'm going to assume you're trying to use those environment variables in your dev environment outside of CodeBuild. Those environment variables are only valid for the life of the container which your CodeBuild project is running on and are there for your build scripts to use. Where ever your code is deployed, won't have those environment variables.
Within our team. We all have our own dev project, and then we have a test and prod environment.
We are currently in the process of migrating from deployment manager, and gcloud cli. Into terraform. however we havent been able to figure out a way to create isolated backends within gcs backend. We have noticed that the remote backends support setting a dedicated workspace but we havent been able to setup something similar within gcs.
Is it possible to state that terraform resource A, will have a configurable backend, that we can adjust per project, or is the equivalent possible with workspaces?
So that we can use either tfvars, and vars parameters to switch between projects?
As stands everytime we attempt to make the backend configurable through vars, we get the error in terraform init of
Error: Variables not allowed
How does one go about creating isolated backends for each project.
Or if that isn't possible how can we guarantee that with multiple projects a shared backend state will not collide causing the state to be incorrect?
Your backend must been known when you run your terraform init command, I mean your backend bucket.
If you don't want to use workspace, you have to customize the backend value before running the init. We are use make to achieve this. According to the environment, make create a backend.tf file with the correct backend name. And run the init command.
EDIT 1
We have this piece of script (sh) which create the backend before triggering the terraform command. (it's our Make file that do this)
cat > $TF_export_dir/backend.tf << EOF
terraform {
backend "gcs" {
bucket = "$TF_subsidiary-$TF_environment-$TF_deployed_application_code-gcs-tfstatebackend"
prefix = "terraform/state"
}
}
EOF
Of course the bucket name pattern is dependent of our project. The $TF_environment is the most important because according to the env var set, the bucket reached will be different.
When I commit to develop branch it must deploy code to specific environment (dev). Similarly when i deploy to uat branch it must deploy to uat environment. How do i achieve this functionality in aws cdk pipeline ?
There is stage and be deployed to multiple region but need to define if pushed to this branch then deploy to this environment likewise.
The best approach depends on a few factors including whether your stack is environment agnostic or not (i.e. whether it needs to look up resources from within a given account.)
For simply switching between different accounts and regions, the CDK team has a decent writeup here which recommends a small wrapper script for each environment that injects the configuration by way of CDK_DEPLOY_ACCOUNT and CDK_DEPLOY_REGION environment variables.
If you want to provide other synth time context then you can do so via the context API, which allows you to provide configuration 'in six different ways':
Automatically from the current AWS account.
Through the --context option to the cdk command.
In the project's cdk.context.json file.
In the project's cdk.json file.
In the context key of your ~/.cdk.json file.
In your AWS CDK app using the construct.node.setContext method.
My team uses the inline context args to define an environment name, and from the environment name, it reads a json config file that defines many environment-dependent parameters.
cdk deploy --context env=Dev
We let the environment name determine the branch name and set it accordingly on the 'Branch' property of the 'GitHubSourceAction'. (C# code)
string env = (string)this.Node.TryGetContext("env");
var pipeline = new CdkPipeline(this, "My-Pipeline", new CdkPipelineProps()
{
SourceAction = new GitHubSourceAction(new GitHubSourceActionProps()
{
Branch = env
})
})
In GOCD we are able to define env variables and parameters for the entire pipeline, stage and individual jobs. Is it possible to update those already defined env variables and parameters via a task in a job when running the pipeline?
Would you like to update them permanently or just for specific execution?
If you would like to do first, I suppose you have to work with config xml, using Pipeline Config REST API.
For latter case you can trigger pipeline with given environment variables set.
In any case, I would recommend you yagocd library, which would let you do both tasks with ease.
I have an EmberCLI app where Staging and Prod both live on the same S3 bucket, and in config/environment.js the environment variable is the same. Still I need to be able to specify different settings for the two "environments".
The surefire way to tell which app is running is by inspecting the domain of the request, but I'm having trouble intercepting that early enough to update my settings.
I've tried creating an initializer to inspect the domain and update the ENV object accordingly, but it seems it's too late in the page lifecycle to have any effect; the page has already been rendered, and my addons do not see their proper settings.
For one addon, I basically had to copy all of its code into my project and then edit the index.js file to use the proper keys based on my domain, but it's unwieldy. Is there a better way to do this? Am I trying to make an architecture work which is just ill-advised?
Any advice from those more versed in Ember would be much appreciated.
There's not a great way to handle staging environments right now (see Stefan Penner's comment here).
That said I think you can achieve a staging environment on s3 by using ember-cli-deploy if you add a staging environment to your ember-cli-deploy config. And handle the difference between staging and production in ember-cli-build.js.
One thing I do is reuse the production environment for both staging and production, but use shell environment variables for some of the configuration:
// config/environment.js
if (environment === 'production') {
ENV.something = process.env.SOMETHING;
}
And then to build:
$ SOMETHING="staging-value" ember build --environment=production
