cp .env.sample .env.dev

Set the OPENAI_API_KEY & TWITTER_BEARER_TOKEN variables in .env.dev

Test the app with Docker Compose

# start docker
service docker start

# Start the app
docker-compose --env-file ".env.dev" up -d --build 

# tail the logs
docker-compose logs --tail="all" -f

Deploying

Deploy the stack with Docker Swarm

# Initialize a docker swarm
sudo docker swarm init 

# Deploy the stack
sudo env $(cat .env.dev | xargs) docker stack deploy --compose-file docker-compose.yaml climate_news_stack 

# Display stack info
sudo docker stack ps climate_news_stack

# Display service info
sudo docker service ps climate_news_stack_news_cron

# Inspect a service
sudo docker service inspect --pretty climate_news_stack_news_cron

# Restart a service
sudo docker service update --force climate_news_stack_news_cron

# Run a command in a container
sudo docker container ls
sudo docker exec -it f855a1118d35 /bin/bash

# Logs for a service
sudo docker service logs -f --since 1h climate_news_stack_db
sudo docker service logs -f --since 1h climate_news_stack_news_api
sudo docker service logs -f --since 1h climate_news_stack_news_cron
sudo docker service logs -f --since 1h climate_news_stack_web
sudo docker service logs -f --since 1h climate_news_stack_caddy

# Search logs for a service
sudo docker service logs --since 24h climate_news_stack_news_cron 2>&1 | grep "tweet_cron_job" 

# Remove the stack
sudo docker stack rm climate_news_stack
sudo docker volume prune
