Seems like some folks claim that we should NOT be using a depends_on in the datasource for the task definition but upon the first run it always fails because the resource doesnt exist. a database, web frontend, and perhaps some for maintenance/cron) is specified in a Task Definition. This is doubly interesting to me. Terraform is a tool that makes it cl e arer. as it stands now the doc's imply that if the resource doesn't exist then nothing should fail. This is doubly interesting to me. This project is part of our comprehensive "SweetOps" approach towards DevOps. and provider.aws v1.10.0. This thread mentions a few other workarounds, but none of them seem to be suitable hashicorp/terraform#16380. 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… The aws_ecs_task_definition is where all the important configuration happens to you container and environment in and around it. You don't have to manually send data ever, the agent simply runs in the background and sends the data for you without blocking your tasks. 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. Which is not the expected/desired result. Version 3.21.0. Wi… @dendrochronology, I use something like this: @KIVagant ahhh, I'm going to play with the ignore_changes lifecycle hook! Furthermore, it's discourage by the Terraform documentation itself. status code: 400, request id: "my-service". I tried also with depends_on and it won't work. 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. It depends on your goals. The ECS container definition data source allows access to details of a specific container within an AWS ECS service. Based on the above docs, OP's config shouldn't be failing because data.aws_ecs_task_definition.my-service depends on aws_ecs_task_definition.my-service.family, but it's failing in the plan* phase (my problem as well). In this case, refreshing the data instance will be deferred until the "apply" phase, and all interpolations of the data instance attributes will show as "computed" in the plan since the values are not yet known. If the task definition is used in a service, you must update that service to use the updated task definition. privacy statement. That's pretty neat. And we control them manually after first install. In my case, the error came out because of json syntax error. It depends on your goals. @radeksimko could we get your eyes on this? Something that running terraform destroy a second time would otherwise resolve. I was able to reproduce this by creating a simple resource first (a security group) then trying to perform a lookup. Ah, nice, I'll play with that, too. You can confirm that your configuration is working by initialising the terraform backend. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. It's only when I have an existing state file that it doesn't work. Which is not the expected/desired result. 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. @KIVagant that makes sense, as I was also experiencing the same issue. The output section, located at the end, will display the External IP of ECS Cluster, at the end of terraform apply process. The text was updated successfully, but these errors were encountered: I'm also experiencing the same issue! 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. In this post, I will try to demonstrate how you can deploy your Docker application into AWS using ECS and Fargate. Already on GitHub? This appears to be a terraform pattern. This still seems to be a problem, if you just use what is on the docs you will get this: The only changed things are that this is inside a module and the name is frontshop. I will use Terraform to spin the infrastructure so I can easily track everything that I create as a code. 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. data.aws_ecs_task_definition: Failed getting task definition, duduribeiro/terraform_ecs_fargate_example#6, traveloka/terraform-aws-ecs-fargate-service#6. At my company we are running on 0.12 and the suggested solution with the conditional on .revision causes an error, as Terraform complains about it not being a boolean value. It is scalable, high-performing container management service that supports Docker containers. This variable needs to be used within a aws_ecs_task_definition resource in the container_definitions. Since anyway both sides of the conditional end up referencing the same value, as a quick fix I used "revision >0" in the conditional just to force it to be a boolean. . You signed in with another tab or window. Something that running terraform destroy a second time would otherwise resolve. Certain variables, such as `healthCheck`, `linuxParameters` On the second pass the. Though I would say the Terraform docs for that show the data object and resource being used together should be updated to reflect this. I deploy new Docker containers to ECS using one task definition per container release (this is usually invoked by a CI job). Published a month ago. NOTE: In Terraform 0.12 and earlier, due to the data resource behavior of deferring the read until the apply phase when depending on values that are not yet known, using depends_on with data resources will force the read to always be deferred to the apply phase, and therefore a configuration that uses depends_on with a data resource can never converge. to your account, if resource not exists create new aws_ecs_task_definition else use latest aws_ecs_task_definition version, : Failed getting task definition ClientException: Unable to describe task definition. 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! This is working around the issue of not having a task definition when the resources are initially rolled out. 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. Edit: incorrectly said it failed in the apply phase instead of the plan phase. 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. Terraform module to generate well-formed JSON documents that are passed to the aws_ecs_task_definition Terraform resource as container definitions. I have the service and task definition configured via terraform and then to deploy I'm using Github actions where it seems I need to define the task definition again. Unfortunately, that's not gonna be addressed, as stated here: hashicorp/terraform#16380 (comment). . 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. At my company we are running on 0.12 and the suggested solution with the conditional on .revision causes an error, as Terraform complains about it not being a boolean value.
