Error : Network Configuration must be provided when networkMode 'awsvpc' is specified
Here's the run-task command with network-configuration included
aws ecs run-task --cluster your-cluster --task-definition your-task:1 --count 1 --launch-type FARGATE --network-configuration "awsvpcConfiguration={subnets=[subnet-0123456789],securityGroups=[sg-0123456789]}"
You will need something like the below (snapshot from what I have at work)
NetworkConfiguration:
AwsvpcConfiguration:
AssignPublicIp: DISABLED
SecurityGroups:
- !Ref ECSServicesSecurityGroup
Subnets:
- Fn::ImportValue: !Sub ${VPCStack}-SubnetPrivateA
- Fn::ImportValue: !Sub ${VPCStack}-SubnetPrivateB
- Fn::ImportValue: !Sub ${VPCStack}-SubnetPrivateC
Please refer to this and this for more details
I think @user2014363's answer is correct, and I was able to use it to run my task. If anyone else is trying to do this in CI, you might not know your subnet/security group IDs ahead of time. I was able to use AWS CLI to grab these (you need to have some way of identifying the subnets/security groups you need, such as filtering by tags):
mytask:
image: python:3.8
stage: deploy
only:
- master
when: manual
before_script:
- pip install awscli
- apt-get -qq update && apt-get -y install jq
