I have a jenkins pipeline where I am executing a cloud formation template that I have stored in Gitlab. But my cloudformation template contains an image parameter, that i need to pass on dynamically from jenkins file. can anybody help me with how to do the same. i have highlighted it in bold.
ContainerDefinitions" : [ { "Image":"amazon/amazon-ecs-sample", ],
To do this you would instead need to make the Image value a parameter passed into the CloudFormation stack.
In your CloudFormation stack create a parameter named "Image" such as below
"Parameters": {
"Image": {
"Type": String,
"Description": "The image name to use within the container definition"
}
}
Then in your code you can reference it using the Ref intrinsic function within the Container Definition like below
ContainerDefinitions" : [ { "Image": { "Ref": "Image" }, ]
When you create the stack using the CLI you would create like this below
aws cloudformation create-stack --stack-name myteststack --template-body file://sampletemplate.json --parameters ParameterKey=Image,ParameterValue=amazon/amazon-ecs-sample
If you're using a parameter in the Jenkins Pipeline you could replace the image name like the below
aws cloudformation create-stack --stack-name myteststack --template-body file://sampletemplate.json --parameters ParameterKey=Image,ParameterValue=${env.Image}
