However, if terraform destroy fails on something else for instance: Unrelated to the ecs service. Edit: incorrectly said it failed in the apply phase instead of the plan phase. 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. Check versions for this module on: This way if you encounter errors, you can troubleshoot minimally, rather than digging through five files for the culprit. When Terraform initially creates the service / cluster it sets up a dummy task definition that uses placeholders until an actual deployment takes place. This ensures that the retrieved data is available for use during planning and the diff will show the real values obtained. I see in this post where the author specify something like. I have multiple projects, each with their own Terraform to manage the AWS infrastructure specific to that project.

It depends on your goals. In this post, I will try to demonstrate how you can deploy your Docker application into AWS using ECS and Fargate. Version 3.20.0. 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. This issue isn't very clear to me. Apparently, this allows Terraform to correctly resolve the dependencies and makes the data source behave as expected. I actually don't need data and resource for the same thing in the same file. Unfortunately, that's not gonna be addressed, as stated here: hashicorp/terraform#16380 (comment). The reason is, that data sources don't handle missing data gracefully. I was able to reproduce this by creating a simple resource first (a security group) then trying to perform a lookup. 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. Ask Question Asked 6 months ago. 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. Apparently, this allows Terraform to correctly resolve the dependencies and makes the data source behave as expected. Could it be related to the module? 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.

And we control them manually after first install. 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. This is working around the issue of not having a task definition when the resources are initially rolled out. Which is not the expected/desired result. Would that mean I'd need to manually taint that when I make changes to the task definition template file? I'm using Terraform v0.11.5 To make this simpler, we will use one role for both permissions.

Published 23 days ago. Then move on to instance.tf and do the terraform apply. The plan for this also failed. The plan failed when a resource was already present in a statefile (the security group in this case). This variable needs to be used within a aws_ecs_task_definition resource in the container_definitions. However, this causes a potential change in the terraform plan output, even though it's not actually going to change. This thread mentions a few other workarounds, but none of them seem to be suitable hashicorp/terraform#16380. See also this issue #1274. Successfully merging a pull request may close this issue. Create an ECS Task Definition I am trying to deploy ECS task definition with Terraform. 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. 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. status code: 400, request id: "my-service".

Terraform import ECS task definition from another project. and provider.aws v1.10.0. and provider.aws v1.10.0. What's curious is that when attempting the search using a vanilla state (completely empty), the plan and apply work as expected. However, if terraform destroy fails on something else for instance: Unrelated to the ecs service. Edit: incorrectly said it failed in the apply phase instead of the plan phase. 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. Check versions for this module on: This way if you encounter errors, you can troubleshoot minimally, rather than digging through five files for the culprit. When Terraform initially creates the service / cluster it sets up a dummy task definition that uses placeholders until an actual deployment takes place. This ensures that the retrieved data is available for use during planning and the diff will show the real values obtained. I see in this post where the author specify something like. I have multiple projects, each with their own Terraform to manage the AWS infrastructure specific to that project. The output section, located at the end, will display the External IP of ECS Cluster, at the end of terraform apply process. Furthermore, it's discourage by the Terraform documentation itself. This Terraform module creates an AWS ECS Fargate task definition. This project is part of our comprehensive "SweetOps" approach towards DevOps. The ECS container definition data source allows access to details of a specific container within an AWS ECS service. Already on GitHub? hashicorp/terraform-provider-aws latest version 3.23.0. It depends on your goals. In this post, I will try to demonstrate how you can deploy your Docker application into AWS using ECS and Fargate. Version 3.20.0. 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. This issue isn't very clear to me. Apparently, this allows Terraform to correctly resolve the dependencies and makes the data source behave as expected. I actually don't need data and resource for the same thing in the same file. Unfortunately, that's not gonna be addressed, as stated here: hashicorp/terraform#16380 (comment). The reason is, that data sources don't handle missing data gracefully. I was able to reproduce this by creating a simple resource first (a security group) then trying to perform a lookup. 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. Ask Question Asked 6 months ago. 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. Apparently, this allows Terraform to correctly resolve the dependencies and makes the data source behave as expected. Could it be related to the module? 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. I tried also with depends_on and it won't work. @radeksimko could we get your eyes on this? Task Role and Task Execution Role. privacy statement. 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. Sign in error resurfaces and the state file is corrupt. Though I would say the Terraform docs for that show the data object and resource being used together should be updated to reflect this. One of the suggested workarounds is, to add an explict depends_on. I commented out the data and now it seems to be working better. I hope you found a solution. Network Resources. @dendrochronology sorry for the lack of response. privacy statement. The text was updated successfully, but these errors were encountered: I'm also experiencing the same issue! You signed in with another tab or window. I am thinking of applying a first version to create the resource and then use the data with max to get the latest revision. This script uses the Task Definition and Service entities in Amazon's ECS to instigate an automatic blue/green deployment. Edit: incorrectly said it failed in the apply phase instead of the plan phase. Then move on to instance.tf and do the terraform apply. Viewed 321 times 1. I don't want to spam the main repo if it's not a terraform issue. I'm new to Terraform, and I'm working on a project to use Docker/AWS ECR/ECS infrastructure on AWS. ; execution_role_arn - (Optional) The Amazon Resource Name (ARN) of the task execution role that the Amazon ECS container agent and the Docker daemon can assume. AWS ECS Fargate Task Definition Terraform Module. Wi… I've noticed that func dataSourceAwsEcsTaskDefinitionRead does not get called in a vanilla project, but does in an existing one. And we control them manually after first install. 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. This is working around the issue of not having a task definition when the resources are initially rolled out. Which is not the expected/desired result. Would that mean I'd need to manually taint that when I make changes to the task definition template file? I'm using Terraform v0.11.5 To make this simpler, we will use one role for both permissions. 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.
