Below is … In my case, the error came out because of json syntax error. Which is not the expected/desired result. You signed in with another tab or window. Creating an ECR repository Successfully merging a pull request may close this issue. See also this issue #1274. as it stands now the doc's imply that if the resource doesn't exist then nothing should fail. 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. 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. In this post, I will try to demonstrate how you can deploy your Docker application into AWS using ECS and Fargate. I don't want to spam the main repo if it's not a terraform issue. 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. In your fargate.tf file from earlier, add the following json into your task definition. The team uses Jupyter Notebooks a lot (locally). . I hope you found a solution. 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. 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. @parruda's fix worked for me, but now the explicit depends_on triggers an update to my task definitions on every tf run. as it stands now the doc's imply that if the resource doesn't exist then nothing should fail. @bentolor Which version of Terraform is that solution valid for? and provider.aws v1.10.0. Terraform module to generate well-formed JSON documents that are passed to the aws_ecs_task_definition Terraform resource as container definitions. On the second pass the. In terraform I am attempting to pass a variable (list) to a module that we built. I deploy new Docker containers to ECS using one task definition per container release (this is usually invoked by a CI job). Here where I found out about it #2026, nice one @jaysonsantos. Published 2 days ago. I see in this post where the author specify something like. @KIVagant that makes sense, as I was also experiencing the same issue. 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. Sign in However, if terraform destroy fails on something else for instance: Unrelated to the ecs service. Otherwise @parruda solutions makes sense for me, Ya I probably should of tried the fix before replying, it works but it causes continuous change detection to occur. I'm using Terraform v0.11.5 Is there a best practice to prevent that? Creating tf file for ECS-EC2-instance; Creating ECS Task Definition; ... user_data.tpl. 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. Perhaps this is a terraform-level bug and not a provider-level? hashicorp/terraform-provider-aws latest version 3.23.0. . data.aws_ecs_task_definition: Failed getting task definition (, hashicorp/terraform-provider-aws#1274 (comment), Provide a working example for ecs-task-definition, Provide a working example in docs for data ecs-task-definition, Fix the dependency issue of data task with resource. 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! 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. This is working around the issue of not having a task definition when the resources are initially rolled out. I actually never noticed the problem because we do want to update the task definition on every run. Ah, nice, I'll play with that, too. 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. 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). The text was updated successfully, but these errors were encountered: I'm also experiencing the same issue! Terraform import ECS task definition from another project. If you are new to Docker, I highly recommend this course by Stephen Grider or the official… . Already on GitHub? For my teams, that means abstracting out the management of the ECS cluster, ALB, Security Groups, R53 rules, databases, and S3 buckets into shared terraform that the platform/SRE team can manage. By clicking “Sign up for GitHub”, you agree to our terms of service and I verified my hypothesis by also creating a different data source which looked up a non-existent security group. Latest Version Version 3.23.0. It's only when I have an existing state file that it doesn't work. privacy statement. The documetation example of directly referecing "task_family" doesn't work and exits with an error when initially applying it. 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. 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. Successfully merging a pull request may close this issue. I'm using Terraform v0.11.5 This issue isn't very clear to me. This is working around the issue of not having a task definition when the resources are initially rolled out. Is there a best practice to prevent that? 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. Certain variables, such as `healthCheck`, `linuxParameters` ECS has two permission models to manage the resources. I commented out the data and now it seems to be working better. This issue isn't very clear to me. I'm new to Terraform, and I'm working on a project to use Docker/AWS ECR/ECS infrastructure on AWS. Network Resources. What's curious is that when attempting the search using a vanilla state (completely empty), the plan and apply work as expected. Check versions for this module on: This thread mentions a few other workarounds, but none of them seem to be suitable hashicorp/terraform#16380. Terraform import ECS task definition from another project. Ask Question Asked 6 months ago. ECS: Task Definition (with multiple containers) Cluster; Service; Launch Config and Auto Scaling Group; Health Checks and Logs; You can find each of the Terraform configuration files in the django-ecs-terraform repo on GitHub. 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). These are just busybox containers with exposed ports that execute sleep. I tried also with depends_on and it won't work. What's curious is that when attempting the search using a vanilla state (completely empty), the plan and apply work as expected. Edit: incorrectly said it failed in the apply phase instead of the plan phase. I commented out the data and now it seems to be working better. Even more curious, the resources don't exist in the statefile anyhow, and yet it fails? Already on GitHub? Usage. Have a question about this project? If you want to learn the basics of Terraform, please read my post about it. And we control them manually after first install. We only use Terraform for the initial provisioning and when we use new services. Furthermore, it's discourage by the Terraform documentation itself. The reason is, that data sources don't handle missing data gracefully. And we control them manually after first install. 14. This project is part of our comprehensive "SweetOps" approach towards DevOps. In my case, the error came out because of json syntax error. This project is part of our comprehensive "SweetOps" approach towards DevOps. It depends on your goals. 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 the container_definitions property, we place definition in JSON format which includes what image we want to run, what environment variables we want to have, where to put the logs etc. One by one, next task, then service then finally alb. That's pretty neat. status code: 400, request id: "my-service". This way if you encounter errors, you can troubleshoot minimally, rather than digging through five files for the culprit. 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. Furthermore, it's discourage by the Terraform documentation itself. Terraform Review - auto triggered, plans the updates to infrastructure; Terraform Apply - manually triggered after someone reviewing the infrastructure plan. Task definitions are split into separate parts: the task family, the IAM task role, the network mode, container definitions, volumes, task placement constraints, and launch types. Published a month ago. See also this issue #1274. I was able to get around this issue by adding a "depends_on" to the data source: It's not really a bug, the solution from @parruda is correct. You signed in with another tab or window. To make this simpler, we will use one role for both permissions. Notable here is that image_tag_mutability is set to be MUTABLE.This is necessary in order to put a latest tag on the most recent image. If terraform destroy completes with no errors, it works fine without a depends_on. status code: 400, request id: "my-service". Which is not the expected/desired result. 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. Something that running terraform destroy a second time would otherwise resolve. error resurfaces and the state file is corrupt. This variable needs to be used within a aws_ecs_task_definition resource in the container_definitions. Could it be related to the module? 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. 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. Published 3 days ago. 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. If not set, ECS will create a nonpersistent data volume that starts empty and is deleted after the task has finished. ... data "aws_ecs_task_definition" "test" {task_definition = "${aws_ecs_task_definition.test.family}" Let's define our network resources in … However, this causes a potential change in the terraform plan output, even though it's not actually going to change.
