The containerOverrides in AWS Batch

With AWS Batch, we may specify runtime changes to the default settings of container properties using the containerOverrides parameter. Using the AWS Cloud, batch computing workloads can be handled through the use of AWS Batch.
We can specify a job specifics that contains different factors when submitting a job to AWS Batch. We can override some of these values on a per-job basis using the “containerOverrides” parameter.

Working

Job Definition:

The parameters for the task, including the container attributes, are specified in the job specification that we produce when we define a job in AWS Batch.

Container Overrides:

The “containerOverrides” option is one that we can add in a task submission. We can alter specific properties given in the job definition that are unique to that job by using this parameter.

Dynamic Setup:

When we wish to reuse a common job definition but have varying resource needs or settings for multiple jobs, this feature comes in handy.

Example

This example uses the “containerOverrides” parameter to override the settings supplied in the job definition and create an environment variable (MY_ENV_VARIABLE) with a custom value for this particular task, setting the RAM requirement to 4096 MB.
