update_task_definition_image.py

import sys, json, argparse

parser = argparse.ArgumentParser('Replaces image in the task definition')
parser.add_argument('image_uri', metavar='I', type=str, nargs='+',
                   help='The new image URI')

args = parser.parse_args()

definition = json.load(sys.stdin)['taskDefinition']['containerDefinitions']
definition[0]['image'] = args.image_uri[0]
print json.dumps(definition)

Note, in Gitlab you can now use $CI_COMMIT_SHORT_SHA instead of "$(echo $CI_COMMIT_SHA | head -c 8)". See: https://docs.gitlab.com/ee/ci/variables/predefined_variables.html#:~:text=is%20built%20for.-,CI_COMMIT_SHORT_SHA,-11.7

Anyone here has a solution to pass a container environment used on applications?

Like injecting this Envs in the task definition.

I have used sed command in my pipeline to inject env vars in task definition file.

    - TASK_DEFINITION=$(aws ecs describe-task-definition --task-definition "$CI_AWS_ECS_TASK_DEFINITION" --region "${AWS_DEFAULT_REGION}")
    - NEW_CONTAINER_DEFINTIION=$(echo $TASK_DEFINITION | jq --arg IMAGE "$DOCKER_REGISTRY/$APP_NAME:latest" '.taskDefinition.containerDefinitions[0].image = $IMAGE | .taskDefinition.containerDefinitions[0]')
    - echo "Registering new container definition..."
    - aws ecs register-task-definition --region "${AWS_DEFAULT_REGION}" --family "${CI_AWS_ECS_TASK_DEFINITION}" --container-definitions "${NEW_CONTAINER_DEFINTIION}"
    - echo "Updating the service..."
    - aws ecs update-service --region "${AWS_DEFAULT_REGION}" --cluster "${CI_AWS_ECS_CLUSTER}" --service "${CI_AWS_ECS_SERVICE}"  --task-definition "${CI_AWS_ECS_TASK_DEFINITION}"

this is the script i'm using however the service deployment does not start the desired task count is 1 however it does not create any

or you can use sed to set the new image tag, in my case, the CI_PIPELINE_IID and then use jq to extract the container definition:

NEW_CONTAINER_DEFINITION=$(echo $TASK_DEFINITION | sed -e "s/ecr-image:.*/ecr-image:$CI_PIPELINE_IID\",/g")
NEW_CONTAINER_DEFINITION=$(echo $NEW_CONTAINER_DEFINITION | jq '.taskDefinition.containerDefinitions[0]')

Actually there was nothing wrong with the script, it was failing to bind a port to the new container because I was using a static port binding.
Later I switched to using gitlab's ecs deployment script

    - TASK_DEFINITION=$(aws ecs describe-task-definition --task-definition "$CI_AWS_ECS_TASK_DEFINITION" --region "${AWS_DEFAULT_REGION}")
    - NEW_CONTAINER_DEFINTIION=$(echo $TASK_DEFINITION | jq --arg IMAGE "$DOCKER_REGISTRY/$APP_NAME:latest" '.taskDefinition.containerDefinitions[0].image = $IMAGE | .taskDefinition.containerDefinitions[0]')
    - echo "Registering new container definition..."
    - aws ecs register-task-definition --region "${AWS_DEFAULT_REGION}" --family "${CI_AWS_ECS_TASK_DEFINITION}" --container-definitions "${NEW_CONTAINER_DEFINTIION}"
    - echo "Updating the service..."
    - aws ecs update-service --region "${AWS_DEFAULT_REGION}" --cluster "${CI_AWS_ECS_CLUSTER}" --service "${CI_AWS_ECS_SERVICE}"  --task-definition "${CI_AWS_ECS_TASK_DEFINITION}"

this is the script i'm using however the service deployment does not start the desired task count is 1 however it does not create any

you can set minimum healthy percent to 0 and maximum percent to 100 if you want only one container running on your ecs.

Getting an error while using was ecr login. Any idea? I'm passing secret key and access ID from CI/CD in variables

Hi Guys,

I have done with my gitlab pipeline one branh (master) and now i have fail with two branh both master, develop branh.

Please help me to wrire into .gitlab-ci.yml one
build:
stage: build
deploy:
stage: deploy

all develop, master branh?

Thank for help and hope see rely soon.

Hi there!
Just finished with ECS FARGATE deployment step at the GitLab CI. Want to share the result.
Hopefully, this would be helpful and save time for someone ;)

- TASK_DEFINITION_CURRENT=$(aws ecs describe-services --services "${ECS_SERVICE_NAME}" --cluster "${ECS_CLUSTER_NAME}" | jq -r .services[].taskDefinition | cut -d "/" -f 2)
- TASK_DEFINTION_NAME=$(echo $TASK_DEFINITION_CURRENT | cut -d ":" -f 1 )
- TASK_DEFINITION=$(aws ecs describe-task-definition --task-definition "$TASK_DEFINTION_NAME")
- NEW_CONTAINER_DEFINTIION=$(echo $TASK_DEFINITION | jq --arg IMAGE "${CI_REGISTRY_IMAGE}/${CI_COMMIT_REF_SLUG}:${DEPLOY_CONTAINER_TAG}" '.taskDefinition.containerDefinitions[0].image = $IMAGE | .taskDefinition.containerDefinitions[0]')
- EXECUTION_ROLE_ARN=$(echo $TASK_DEFINITION | jq -r '.taskDefinition.executionRoleArn')
- TASK_ROLE_ARN=$(echo $TASK_DEFINITION | jq -r '.taskDefinition.taskRoleArn')
- CONTAINER_MEMORY=$(echo $TASK_DEFINITION | jq -r '.taskDefinition.memory')
- CONTAINER_CPU=$(echo $TASK_DEFINITION | jq -r '.taskDefinition.cpu')
- REQUIRE_COMPATABILITIES=$(echo $TASK_DEFINITION | jq -r '.taskDefinition.requiresCompatibilities[]')
- NETWORK_MODE=$(echo $TASK_DEFINITION | jq -r '.taskDefinition.networkMode')
- echo "Registering new container definition..."
- aws ecs register-task-definition --family "${TASK_DEFINTION_NAME}" --container-definitions "${NEW_CONTAINER_DEFINTIION}" --execution-role-arn "${EXECUTION_ROLE_ARN}" --memory "${CONTAINER_MEMORY}" --requires-compatibilities "${REQUIRE_COMPATABILITIES}" --network-mode "${NETWORK_MODE}" --cpu "${CONTAINER_CPU}"  --task-role-arn "${TASK_ROLE_ARN}"
- echo "Updating the service..."
- aws ecs update-service --cluster "${ECS_CLUSTER_NAME}" --service "${ECS_SERVICE_NAME}"  --task-definition "${TASK_DEFINTION_NAME}"

to avoid python you can use jq

- NEW_CONTAINER_DEFINTIION=$(echo $TASK_DEFINITION | jq --arg IMAGE "$REPOSITORY_URL:$IMAGE_TAG" '.taskDefinition.containerDefinitions[0].image = $IMAGE | .taskDefinition.containerDefinitions[0]')

Hi,
Is there anyway we can pass two container images with this? I have been trying to work around this and could not find any solutions.

Hi Team ,

ia m getting below vunrability how to fix any one pls help

Improper access control in the Intel(R) Ethernet Controller RDMA driver for linux before version 1.9.30 may allow an unauthenticated user to potentially enable escalation of privilege via network access.

Hi Team ,

i am using for deployment below script

scripts:

  • echo "Updating the service..."
  • aws ecs update-service --cluster "${CLUSTER_NAME}" --service "${SERVICE_NAME}" --task-definition "${TASK_DEFINTION_NAME}"

but i am getting below error

“message”: “(service crm-api-secured) failed to launch a task with (error ECS was unable to assume the role ‘arn:aws:iam::XXXXXXXXX:role/null’ that was provided for this task.

any one pls help for the same.
