The resource aws_ecs_service and the data aws_ecs_task_definition both expect that related resource aws_ecs_task_definition must be already created. FYI for everybody else stumbling over the issue: @skorfmann illustrated in this MR #10247 a better workaround using aws_ecs_task_definition.self.revision and explains why the discussed depends_on approach is not what you want! Published 23 days ago. I don't want to spam the main repo if it's not a terraform issue. Could it be related to the module? We only use Terraform for the initial provisioning and when we use new services. All composite types (e.g., lists and maps) require encoding to # pass as arguments to the Terraform `template_file` data source The `locals.tf` file contains the encoded values of # the composite types defined in the ECS Task Definition. Is there a best practice to prevent that? @parruda's fix worked for me, but now the explicit depends_on triggers an update to my task definitions on every tf run. I actually don't need data and resource for the same thing in the same file. Then move on to instance.tf and do the terraform apply. . I don't want to spam the main repo if it's not a terraform issue. Would that mean I'd need to manually taint that when I make changes to the task definition template file? Task Role and Task Execution Role. Terraform import ECS task definition from another project. @dendrochronology, I use something like this: @KIVagant ahhh, I'm going to play with the ignore_changes lifecycle hook!

With Terraform, the ECS task definition will be implemented in order to run Docker containers: resource "aws_ecs_task_definition" "definition" {} For a task definition of an ECS task, there are a series of parameters that will be used. What I added is a so-called lifecycle policy, to make sure I don’t keep too many versions of image, as with every new deployment of the application, a new image would be created. The reason is, that data sources don't handle missing data gracefully. Wi… Perhaps this is a terraform-level bug and not a provider-level? If the arguments of a data instance contain no references to computed values, such as attributes of resources that have not yet been created, then the data instance will be read and its state updated during Terraform's "refresh" phase, which by default runs prior to creating a plan. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. It is scalable, high-performing container management service that supports Docker containers. In this post, I will try to demonstrate how you can deploy your Docker application into AWS using ECS and Fargate. On a first glance, the only thing that I needed was to specify on the task definition the version of Fargate to 1.4.0, but since I never worked with EFS before, and the Terraform docs forget to mention that you need to implement others resources to work with EFS properly, I suffered a little bit to figure out what I needed to get done. It's only when I have an existing state file that it doesn't work. terraform apply -auto-approve terraform state rm aws_ecs_task_definition.this Next time these scripts are executed (and something has changed in task definition), the terraform does not know about the previous task definition (as it is not in its state) and therefore creating new version instead and dont delete old version. 14. This script uses the Task Definition and Service entities in Amazon's ECS to instigate an automatic blue/green deployment. To make this simpler, we will use one role for both permissions. Terraform module to generate well-formed JSON documents that are passed to the aws_ecs_task_definition Terraform resource as container definitions. Actually, what I said is a lie, looks like there is a problem when you have an invalid JSON for container definitions and mine is not using the heredoc syntax but a json file with a template and it should be an array of containers and i have only one main object. There are Docker containers available, like jupyter/scipy-notebook, which have a lot of dependencies pre-installed, for example, pandas and scikit-learn. I commented out the data and now it seems to be working better. If the task definition is used in a service, you must update that service to use the updated task definition. Data instance arguments may refer to computed values, in which case the attributes of the instance itself cannot be resolved until all of its arguments are defined. So, we wanted to be able to spin up a Jupyter Notebook in the cloud without too much hassle, if possible even a separate instance for everyone, so dependencies, resource… If the arguments of a data instance contain no references to computed values, such as attributes of resources that have not yet been created, then the data instance will be read and its state updated during Terraform's "refresh" phase, which by default runs prior to creating a plan. The documetation example of directly referecing "task_family" doesn't work and exits with an error when initially applying it. We’ll occasionally send you account related emails. @KIVagant that makes sense, as I was also experiencing the same issue. The resource aws_ecs_service and the data aws_ecs_task_definition both expect that related resource aws_ecs_task_definition must be already created. I actually never noticed the problem because we do want to update the task definition on every run. The text was updated successfully, but these errors were encountered: I'm also experiencing the same issue!

Exporting AWS Data Pipeline as CloudFormation template to use it in Terraform. The team uses Jupyter Notebooks a lot (locally). aws_ecs_task_definition.self.revision can only be referenced, once the resource is created (in contrast to family, which is already present in code). Creating an ECR repository This issue isn't very clear to me. and provider.aws v1.10.0. Successfully merging a pull request may close this issue. Amazon ECS is a service for running and maintaining a specified number of task. Let's define our network resources in … I see in this post where the author specify something like. I'm using Terraform v0.11.5 One is Task Role to assume role access for container and another is Task Execution Role for ECS cluster to run on behalf of us, such as pulling image. I actually never noticed the problem because we do want to update the task definition on every run. as it stands now the doc's imply that if the resource doesn't exist then nothing should fail. The name is usedto refer to this resource from elsewhere in the same Terraform module, but hasno significance outside of the scope of a module. error resurfaces and the state file is corrupt. task_role_arn - (Optional) The ARN of IAM role that allows your Amazon ECS container task to make calls to other AWS services. Could it be related to the module? In our case the template contains empty place for secrets which are filling after first install by Terraform and we don't want to allow it to change exist task definitions. What's curious is that when attempting the search using a vanilla state (completely empty), the plan and apply work as expected. Data instance arguments may refer to computed values, in which case the attributes of the instance itself cannot be resolved until all of its arguments are defined. List of available providers can be found here: In order to allow communication between instances in our VPC and the internet we need to create The only required parameter is a previously created VPC id that can be obtain by invoking To create a subnet we need to provide VPC id and CIDR block.

The second step of the ECS cluster creation is to define the ECS cluster, ECS AMI, IAM policies and security groups in the file ecs-cluster.tf. An idea we came up with, was to easily spin up a Docker container on AWS based on that image, which then could be used by a team member. I tried also with depends_on and it won't work. @bentolor Which version of Terraform is that solution valid for? Though I would say the Terraform docs for that show the data object and resource being used together should be updated to reflect this.
