⁠Using the Docker Container

⁠Building the Container

if you have problems use the --no-cache option

docker build -t dronzebot/snswebhook:latest .

⁠Running The Docker image

The container will use the configuration and brain graph you provide.

$ docker run -t -d -p 5020:5020 --name snswebhook -v ${CONFIG_DIR}:/mnt/config dronzebot/snswebhook:latest

⁠Pushing the Container to AWS ECR

1. Retrieve the docker login command that you can use to authenticate your Docker client to your registry:

aws ecr get-login --region us-west-2

1. Run the docker login command that was returned in the previous step.
2. Build your Docker image using the following command. For information on building a Docker file from scratch see the instructions here. You can skip this step if your image is already built:

docker build -t dronzebot/snswebhook:latest .

1. After the build completes, tag your image so you can push the image to this repository:

docker tag dronzebot/snswebhook:latest 604212546939.dkr.ecr.us-west-2.amazonaws.com/dronzebot/snswebhook:latest

1. Run the following command to push this image to your newly created AWS repository:

docker push 604212546939.dkr.ecr.us-west-2.amazonaws.com/dronzebot/snswebhook:latest

⁠Pulling the Container from the Private Repo and Running

1. login

aws ecr get-login --region us-west-2

1. pull the container from the ecs repo

docker pull 604212546939.dkr.ecr.us-west-2.amazonaws.com/dronzebot/snswebhook:latest

1. make sure that the snswebhook.properties is in the config dir to be mounted.

2. make sure any existing instances are stoped and removed

$ sudo docker stop snswebhook
snswebhook
$ sudo docker rm snswebhook
snswebhook

1. run it

$ export CONFIG_DIR=/home/ubuntu/config
$ docker run -t -d --name snswebhook -v ${CONFIG_DIR}:/mnt/config 604212546939.dkr.ecr.us-west-2.amazonaws.com/dronzebot/snswebhook:latest
