|
|
|
|
### 3. Set Up Swap (Recommended for servers with limited RAM)

|
```
|
|
|
|

|
|
|
|
## Install Dokku
|
|
|
|
### 1. Download and Install Dokku
|
|
|
|
```bash
|
|
# Download the installation script
|
|
wget -NP . https://dokku.com/install/v0.34.4/bootstrap.sh
|
|
|
|
# Run the installer (takes 5-10 minutes)
|
|
sudo DOKKU_TAG=v0.34.4 bash bootstrap.sh
|
|
```
|
|
|
|
### 2. Configure Dokku
|
|
|
|
```bash
|
|
# Set your domain (replace with your actual domain)
|
|
dokku domains:set-global casera.treytartt.com
|
|
|
|
# Add your SSH public key for deployments
|
|
# Run this from your LOCAL machine:
|
|
cat ~/.ssh/id_rsa.pub | ssh root@your-server-ip dokku ssh-keys:add admin
|
|
```
|
|
|
|
### 3. Install Required Plugins
|
|
|
|
```bash
|
|
# PostgreSQL plugin
|
|
dokku plugin:install https://github.com/dokku/dokku-postgres.git postgres
|
|
|
|
# Redis plugin
|
|
dokku plugin:install https://github.com/dokku/dokku-redis.git redis
|
|
|
|
# Let's Encrypt plugin (for SSL)
|
|
dokku plugin:install https://github.com/dokku/dokku-letsencrypt.git
|
|
```
|
|
|
|
---
|
|
|
|
## Create the App
|
|
|
|
### 1. Create the Dokku App
|
|
|
|
```bash
|
|
dokku apps:create casera-api
|
|
```
|
|
|
|
### 2. Set the Domain
|
|
|
|
```bash
|
|
dokku domains:add casera-api api.casera.treytartt.com
|
|
```
|
|
|
|
### 3. Configure Buildpack (if needed)
|
|
|
|
The app uses a Dockerfile, so Dokku will auto-detect it. If you need to force Docker builds:
|
|
|
|
```bash
|
|
dokku builder:set casera-api build-dir .
|
|
dokku builder-dockerfile:set casera-api dockerfile-path Dockerfile
|
|
```
|
|
|
|
---
|
|
|
|
## Configure PostgreSQL
|
|
|
|
### 1. Create PostgreSQL Service
|
|
|
|
```bash
|
|
# Create the database service
|
|
dokku postgres:create casera-db
|
|
|
|
# Link to the app (automatically sets DATABASE_URL)
|
|
dokku postgres:link casera-db casera-api
|
|
```
|
|
|
|
### 2. Verify Connection
|
|
|
|
```bash
|
|
# Check the connection info
|
|
dokku postgres:info casera-db
|
|
|
|
# Connect to the database
|
|
dokku postgres:connect casera-db
|
|
```
|
|
|
|
### 3. Set Individual Database Variables
|
|
|
|
Dokku sets `DATABASE_URL` automatically, but the app expects individual variables:
|
|
|
|
```bash
|
|
# Get the database credentials
|
|
dokku postgres:info casera-db
|
|
|
|
# Set individual variables (replace with actual values from info command)
|
|
dokku config:set casera-api \
|
|
DB_HOST=dokku-postgres-casera-db \
|
|
DB_PORT=5432 \
|
|
POSTGRES_DB=casera_db \
|
|
POSTGRES_USER=postgres \
|
|
POSTGRES_PASSWORD=1mJPfu6rzG9r6xukcGbUOU5NoCg0jKfa
|
|
```
|
|
|
|
---
|
|
|
|
## Configure Redis
|
|
|
|
### 1. Create Redis Service
|
|
|
|
```bash
|
|
# Create the Redis service
|
|
dokku redis:create casera-redis
|
|
|
|
# Link to the app (automatically sets REDIS_URL)
|
|
dokku redis:link casera-redis casera-api
|
|
```
|
|
|
|
### 2. Verify Connection
|
|
|
|
```bash
|
|
dokku redis:info casera-redis
|
|
```
|
|
|
|
---
|
|

|
|
|
|
## Configure Storage
|
|
|
|
### 1. Create Persistent Storage Directory
|
|
|
|
```bash
|
|
# Create storage directory on host
|
|
mkdir -p /var/lib/dokku/data/storage/casera-api/uploads
|
|
|
|
# Set permissions
|
|
chown -R 32767:32767 /var/lib/dokku/data/storage/casera-api
|
|
```
|
|
|
|
### 2. Mount Storage to App
|
|
|
|
```bash
|
|
dokku storage:mount casera-api /var/lib/dokku/data/storage/casera-api/uploads:/app/uploads
|
|
```
|
|
|
|
---
|
|
|
|
## Deploy the Application
|
|
|
|
### 1. Add Dokku Remote (Local Machine)
|
|
|
|
```bash
|
|
cd /path/to/myCribAPI-go
|
|
git remote add dokku dokku@your-server-ip:casera-api
|
|
```
|
|
|
|
### 2. Deploy
|
|
|
|
```bash
|
|
git push dokku master:main
|
|
# Or if your branch is already 'main':
|
|
git push dokku main
|
|
```
|
|
|
|
### 3. Watch Deployment Logs
|
|
|
|
```bash
|
|
# On server
|
|
dokku logs casera-api -t
|
|
```
|
|
|
|
### 4. Verify Deployment
|
|
|
|
```bash
|
|
# Check app status
|
|
dokku ps:report casera-api
|
|
|
|
# Check app is running
|
|
curl https://api.casera.treytartt.com/api/health/
|
|
```
|
|
|
|
---
|
|
|
|
## Configure SSL
|
|
|
|
### 1. Set Let's Encrypt Email
|
|
|
|
```bash
|
|
dokku letsencrypt:set casera-api email admin@treytartt.com
|
|
```
|
|
|
|
### 2. Enable Let's Encrypt
|
|
|
|
```bash
|
|
dokku letsencrypt:enable casera-api
|
|
```
|
|
|
|
### 3. Set Up Auto-Renewal
|
|
|
|
```bash
|
|
dokku letsencrypt:cron-job --add
|
|
```
|
|
|
|
---
|
|
|
|
## Set Up Worker Process
|
|
|
|
The worker process handles background jobs (task reminders, email sending, etc.).
|
|
|
|
### 1. Create Procfile (if not exists)
|
|
|
|
The Dockerfile already handles this, but if you need a Procfile:
|
|
|
|
```bash
|
|
# In your local repo, create Procfile:
|
|
echo "web: /app/api" > Procfile
|
|
echo "worker: /app/worker" >> Procfile
|
|
```
|
|
|
|
### 2. Scale Worker Process
|
|
|
|
```bash
|
|
# Scale to 1 worker
|
|
dokku ps:scale casera-api worker=1
|
|
|
|
# Verify processes
|
|
dokku ps:report casera-api
|
|
```
|
|
|
|

|
|
|
|
#### 7. Set Proxy Port
|
|
|
|
```bash
|
|
dokku proxy:ports-set gorush http:80:8080
|
|
```
|
|
|
|
#### 8. Restart Gorush
|
|
|
|
```bash
|
|
dokku ps:restart gorush
|
|
```
|
|
|
|
#### 9. Configure Casera API to Use Gorush
|
|
|
|
```bash
|
|
dokku config:set casera-api GORUSH_URL=http://gorush.web:8080
|
|
```
|
|
|
|
#### 10. Verify Gorush is Running
|
|
|
|
```bash
|
|
# Check status
|
|
dokku ps:report gorush
|
|
|
|
# Check logs
|
|
dokku logs gorush
|
|
|
|
# Test health endpoint (if you have a domain set)
|
|
curl http://gorush.yourdomain.com/api/stat/go
|
|
```
|
|
|
|
### Option B: Use External Push Service
|
|
|
|
Configure the app to use an external push notification service instead.
