Deploy LogPaste to fly.io

fly.io is the best host I've found for LogPaste. You can run up to three instances 24/7 for a month under their free tier, which includes free SSL certificates.

Pre-requisites

You'll need:

  • A fly.io account (with billing activated)
  • The fly CLI already installed and authenticated on your machine
  • A storage bucket and IAM credentials on Amazon S3 or an S3-compatible storage service

Set your environment variables

To begin, create environment variables for your AWS settings:

LITESTREAM_ACCESS_KEY_ID=YOUR-ACCESS-ID
LITESTREAM_SECRET_ACCESS_KEY=YOUR-SECRET-ACCESS-KEY
LITESTREAM_REGION=YOUR-REGION
DB_REPLICA_URL=s3://your-bucket-name/db

Create your app

Next, create your app on fly.io:

RANDOM_SUFFIX="$(head /dev/urandom | tr -dc 'a-z0-9' | head -c 6 ; echo '')"
APP_NAME="logpaste-${RANDOM_SUFFIX}"

curl -s -L https://raw.githubusercontent.com/mtlynch/logpaste/master/dev-scripts/make-fly-config | \
  bash /dev/stdin "${APP_NAME}"

fly init "${APP_NAME}" --nowrite

Save AWS credentials

Use the fly secrets set command to securely save your AWS credentials to your app:

fly secrets set \
  "LITESTREAM_ACCESS_KEY_ID=${LITESTREAM_ACCESS_KEY_ID}" \
  "LITESTREAM_SECRET_ACCESS_KEY=${LITESTREAM_SECRET_ACCESS_KEY}"

Deploy

Finally, it's time to deploy your app.

# Change this to the latest Docker image tag
LOGPASTE_IMAGE="mtlynch/logpaste:0.2.5"

fly deploy \
  --env "LITESTREAM_REGION=${LITESTREAM_REGION}" \
  --env "DB_REPLICA_URL=${DB_REPLICA_URL}" \
  --image "${LOGPASTE_IMAGE}"

LOGPASTE_URL="https://${APP_NAME}.fly.dev/"
echo "Your LogPaste instance is now ready at: ${LOGPASTE_URL}"

Testing your instance

You can test the instance with this command:

echo "hello, new fly.io instance!" | \
  curl -F '_=<-' "${LOGPASTE_URL}"
