ecsub

1. Dependency

• awscli
• boto3
• pytz
• six

2. Install

Dependent packages are installed automatically.

pip install awscli boto3 pyyaml --upgrade
git clone https://github.com/aokad/ecsub.git
cd ecsub
python setup.py build install

3. Setup

3.1 local machine

First, set up aws configure.

aws configure
    AWS Access Key ID [None]: <YOUR ACCESS KEY>
    AWS Secret Access Key [None]: <YOUR SECRET ACCESS KEY>
    Default region name [None]: <REGION>
    Default output format [None]: json

Next, create your S3_bucket, as follows.

aws s3 mb s3://yourbucket

Optionally, push your docker image (requires python) to dockerhub or Amazon ECR.

3.2 AWS IAM

UserGroup:

1. Create "ecsub-user" group, then attach the following policies.

• AmazonEC2FullAccess
• AmazonECS_FullAccess
• S3_S3FullAccess (It is better to limit "Resource:")
• AWSPriceListServiceFullAccess
• CloudWatchLogsFullAccess
• CloudWatchReadOnlyAccess

Role:

1. Create "ecsInstanceRole" role with AWS EC2, then attach the following policies.

• AmazonEC2ContainerServiceforEC2Role
• S3_S3FullAccess
• CloudWatchMetricFullAccess（create yourself. Choose "CloudWatch:*Metric*"）

2. Edit trust, add "allow ecs-tasks"

{
  "Version": "2008-10-17",
  "Statement": [
    {
      "Sid": "",
      "Effect": "Allow",
      "Principal": {
        "Service": ["ecs-tasks.amazonaws.com", "ec2.amazonaws.com"]
      },
      "Action": "sts:AssumeRole"
    }
  ]
}

3) Download log files

ecsub creates logs on AWS CloudWatch. If you need, you can download log-files to local directory, and remove log-streams from AWS.

$ ecsub logs
usage: ecsub logs [-h] [--wdir path/to/dir]
                  [--log-group-prefix ecsub-task-wordcount]
                  [--log-group-name ecsub-task-wordcount-aBc012]
                  [--log-stream-prefix ecsub/log-stream-name-prefix] [--tail]
                  {download,remove-log-group,remove-log-stream}

For example,

1. download log

# all streams
ecsub logs download --wdir /tmp/ecsub --log-group-prefix ecsub-task-wordcount

# specify streams
ecsub logs download --wdir /tmp/ecsub --log-group-name ecsub-task-wordcount-aBc012 --log-stream-prefix ecsub/task-wordcount-aBc012_tasks/xxx

# last event
ecsub logs download --wdir /tmp/ecsub --log-group-name ecsub-task-wordcount --tail
ecsub logs download --wdir /tmp/ecsub --log-group-name ecsub-task-wordcount-aBc012 --log-stream-prefix ecsub/task-wordcount-aBc012_tasks/xxx --tail

2. remove log-groups

ecsub logs remove-log-group --log-group-prefix ecsub-task-wordcount

3. remove log-streams

ecsub logs remove-log-stream --log-group-name ecsub-task-wordcount-aBc012 --log-stream-prefix ecsub/task-wordcount-aBc012_tasks/xxx

4) Delete jobs.

Attention! If task ends normally (exit with 0, 1, 255...), it does not need to be executed.
delete subcommand is used for jobs that have a creation date ("instance_createAt") but no end date ("instance_stopAt") as shown below.

| exitCode| taskname|  no| ... |    instance_createAt| instance_stopAt| log_local|
|       NA|  sample3| 000| ... | 2019/01/25 17:14:58 |                |          |

$ ecsub delete --help
usage: ecsub delete [-h] [--wdir path/to/dir] task-name

positional arguments:
  task-name           task name

optional arguments:
  -h, --help          show this help message and exit
  --wdir path/to/dir  {PATH} when 'ecsub submit --wdir {PATH}'

For example,

ecsub delete --wdir /tmp/ecsub sample2-bRnfG
