That solution prevent to use Cloud SQL for 4 | development database or for non-critical and low usage production database. 5 | 6 | A [Medium Article](https://medium.com/google-cloud/serverless-database-on-cloud-run-1a930eb00618) describes the 7 | use case and the path to the target solution 8 | 9 | # Technical overview 10 | 11 | There is 2 parts at that solution 12 | 13 | * the serverless sql container 14 | * the serverless database proxy 15 | 16 | # Quick links 17 | 18 | * Packaged container to deploy on Cloud Run (or elsewhere): 19 | * Cloud Storage option: `us-central1-docker.pkg.dev/gblaquiere-dev/public/serverless-sql` 20 | * Cloud Filestore option: `us-central1-docker.pkg.dev/gblaquiere-dev/public/serverless-sql-filestore` 21 | * Compiled serverless db proxy 22 | * [Windows/amd64](https://storage.googleapis.com/serverless-db-proxy/win64/serverless-db-proxy.exe) 23 | * [Linux/amd64](https://storage.googleapis.com/serverless-db-proxy/linux64/serverless-db-proxy) 24 | * [Darwin/amd64](https://storage.googleapis.com/serverless-db-proxy/darwin64/serverless-db-proxy) 25 | * Serverless DB proxy container 26 | * `us-central1-docker.pkg.dev/gblaquiere-dev/public/serverless-db-proxy` 27 | * Serverless DB proxy startup script 28 | * [Linux/amd64](https://storage.googleapis.com/serverless-db-proxy/startup.sh) 29 | 30 | ## Serverless sql container 31 | 32 | That container is composed of 2 parts 33 | 34 | * The database engine itself that run as background process in the container 35 | * The HTTP interface that serve the traffic. 36 | 37 | The process is the following 38 | 1. The database engine starts when the container starts. The data are loaded from Cloud Storage, gunzip and untar 39 | 2. The database engine runs in the container and use the data loaded in the memory of the container 40 | 3. When the container is stopped (signals TERM or INT received), the data are tar and gzip and sent to Cloud Storage 41 | 42 | The use of the HTTP endpoint is described in the "Communication between the 2 parties" section 43 | 44 | ## Serverless database proxy 45 | 46 | The proxy listen the TCP communication and act as proxy to forward them to the serverless sql Cloud Run service. 47 | 48 | ## Communication between the 2 parts 49 | 50 | Cloud Run only accept HTTP connection and disallow TCP connection. That's why, the TCP communication with the database 51 | must be wrapped in HTTP protocol. 52 | 53 | For that, the proxy and the Serverless SQL container open HTTP/2 connection and use bidirectional streaming to 54 | exchange data. The proxy initiate the connection. 55 | 56 | # Deployment of the database 57 | 58 | There is 2 flavors: 59 | 1. Use Cloud Storage to load and store the database data 60 | 2. Use Cloud Filestore to mount a NFS share and use it as data storage 61 | 62 | ## Cloud Storage option 63 | 64 | To deploy the database on Cloud Run follow these steps: 65 | 66 | 1. Create a bucket (you can also reuse an existing one) and, optionally, activate the versioning and set a lifecycle to 67 | limit the versioning depth and cost 68 | ```Bash 69 | # Create the bucket 70 | gsutil mb gs:// 71 | 72 | # Optional, activate the versioning 73 | gsutil versioning set on gs:// 74 | 75 | # Optional, set a lifecycle to limit versioning depth. Here keep 10 backup versions 76 | cat > lifecycle.json << EOF 77 | { 78 | "lifecycle": { 79 | "rule": [ 80 | { 81 | "action": {"type": "Delete"}, 82 | "condition": { 83 | "numNewerVersions": 10, 84 | "isLive": false 85 | } 86 | } 87 | ] 88 | } 89 | } 90 | EOF 91 | 92 | gsutil lifecycle set lifecycle.json gs:// 93 | 94 | ``` 95 | 2. (optional) Create a service account with the permission to read and write to the bucket 96 | ```Bash 97 | # Create the service account 98 | gcloud iam service-accounts create 99 | 100 | # Get the SA email 101 | gcloud iam service-accounts list --format="value(email)" | grep 102 | 103 | # Grant the permission on the bucket 104 | gsutil iam ch serviceAccount::objectAdmin gs:// 105 | ``` 106 | 3. Deploy the container to Cloud Run 107 | ```Bash 108 | gcloud beta run deploy \ 109 | --region= \ 110 | --image=us-central1-docker.pkg.dev/gblaquiere-dev/public/serverless-sql \ 111 | --service-account= #optional. Must have the permission on the bucket \ 112 | --allow-unauthenticated #optionnal. If not, proxy must use authenticated mode \ 113 | --execution-environment gen2 \ 114 | --max-instances=1 \ 115 | --platform=managed \ 116 | --memory=1024Mi \ 117 | --use-http2 \ 118 | --set-env-vars=BUCKET=,ROOT_PASSWORD= 119 | ``` 120 | 121 | **Parameters' explanation** 122 | 123 | * **service-account**: *optional*. Must have the permission on the bucket 124 | * **allow-unauthenticated**: *optional*. If not set, proxy must use authenticated mode 125 | * **execution-environment**: The gen2 runtime isn't sandboxed and you won't have runtime warning because of that 126 | sandbox. But also work on gen1 runtime 127 | * **max-instances**: multi master isn't possible. Only 1 instance can be use at a time. 128 | * **memory**: minimum memory to load the database engine and data in memory. Must be increase if the database 129 | becomes bigger. 130 | * **use-http2**: HTTP/2 protocol in bidirectional streaming is used to communicate between the proxy and the service 131 | * **set-env-vars**: Minimal environment variable: 132 | * **BUCKET**: Name of the bucket to get and store the database data 133 | * **ROOT_PASSWORD**: Root password to connect to the database. The root password can be stored in 134 | [Secret Manager](https://cloud.google.com/secret-manager). In that case, the `ROOT_PASSWORD` must be provided in 135 | that format `sm://projects//secrets//versions/`. And the Cloud Run service account 136 | must have the access permission to the secret `roles/secretmanager.secretAccessor`. 137 | 138 | Use the URL provided by the deployment in the proxy to connect it 139 | 140 | ## Cloud Filestore option 141 | 142 | To deploy the database on Cloud Run follow these steps: 143 | 144 | 1. Create a Cloud Filestore storage in a region. Use the same region as your Cloud Run deployment for better 145 | performances. 146 | ```Bash 147 | gcloud filestore instances create serverless-mysql \ 148 | --tier=STANDARD \ 149 | --zone=us-central1-a \ 150 | --file-share=name=mysql_data,capacity=1TiB \ 151 | --network=name="default" 152 | ``` 153 | 2. Create a serverless VPC connector to bridge the serverless world where run Cloud Run and your VPC on which Cloud 154 | Filestore is attached 155 | ```Bash 156 | gcloud compute networks vpc-access connectors create serverless-mysql \ 157 | --region us-central1 \ 158 | --range "10.8.0.0/28" 159 | ``` 160 | 3. Deploy the container (filestore version) to Cloud Run with the serverless VPC connector and the Cloud Filestore IP 161 | ```Bash 162 | gcloud beta run deploy \ 163 | --region= \ 164 | --image=us-central1-docker.pkg.dev/gblaquiere-dev/public/serverless-sql-filestore \ 165 | --service-account= #optional. Must have the permission on the bucket \ 166 | --allow-unauthenticated #optionnal. If not, proxy must use authenticated mode \ 167 | --execution-environment gen2 \ 168 | --max-instances=1 \ 169 | --platform=managed \ 170 | --memory=512Mi \ 171 | --use-http2 \ 172 | --vpc-connector serverless-mysql \ 173 | --set-env-vars=ROOT_PASSWORD=,FILESTORE_IP_ADDRESS=$(gcloud filestore instances describe serverless-mysql --format "value(networks.ipAddresses[0])" --zone=us-central1-a),FILE_SHARE_NAME=mysql_data 174 | ``` 175 | 176 | **Parameters' explanation** 177 | 178 | * **service-account**: *optional*. Must have the permission on the bucket 179 | * **allow-unauthenticated**: *optional*. If not set, proxy must use authenticated mode 180 | * **execution-environment**: The gen2 runtime isn't sandboxed and you won't have runtime warning because of that 181 | sandbox. Gen2 allows to mount network drive, like NFS. Doesn't work with gen1 182 | * **max-instances**: multi master isn't possible. Only 1 instance can be use at a time. 183 | * **memory**: minimum memory to load the database engine. Must be increase if the database becomes bigger. 184 | * **use-http2**: HTTP/2 protocol in bidirectional streaming is used to communicate between the proxy and the service 185 | * **set-env-vars**: Minimal environment variable: 186 | * **ROOT_PASSWORD**: Root password to connect to the database. The root password can be stored in 187 | [Secret Manager](https://cloud.google.com/secret-manager). In that case, the `ROOT_PASSWORD` must be provided in 188 | that format `sm://projects//secrets//versions/`. And the Cloud Run service account 189 | must have the access permission to the secret `roles/secretmanager.secretAccessor`. 190 | * **FILESTORE_IP_ADDRESS**: IP of the Cloud Filestore. *Here automatically recovered with a gcloud command* 191 | * **FILE_SHARE_NAME**: File share name define in Cloud Filestore. *You can add subpath if required.* 192 | 193 | Use the URL provided by the deployment in the proxy to connect it 194 | 195 | ## Cloud Storage and Cloud Filestore: How to make the choice. 196 | 197 | Cloud Storage is the cheapest solution but not the strongest. Indeed, in case of container crash (out of memory for 198 | insance), or in case of double instance (case where you deploy a new version with new parameters), you can have 199 | data loss. In addition, the cold start, the first start of the Cloud Run instance when no one are provisioned, is long 200 | (about 7s). 201 | 202 | Cloud Filestore solves all that issues, but the 1Tb min capacity of Filestore create an expensive solution (about $200 203 | per month), plus the serverless VPC connector (min $17 per month). That solution cost $217 per month, even if you don't 204 | use it. 205 | 206 | # Use of the proxy 207 | 208 | The proxy wrap the database TCP client connection in HTTP/2 protocol and call the serverless sql service running on 209 | Cloud Run (but can run elsewhere) 210 | 211 | Download the version of the proxy for your environment (see "Quick Links") 212 | 213 | ## Proxy parameters 214 | 215 | You can configure the proxy with different parameters 216 | * **url**: Set the URL of the serverless database service to connect. If not set or set to empty string, the proxy 217 | exit gracefully. 218 | * **port**: The local port to listen. `3306` by default. 219 | * **no-tls**: Deactivate the TLS support for HTTP/2 protocol (activate the clear text mode -> h2c). False by default, 220 | only for local tests 221 | 222 | Example 223 | ```Bash 224 | serverless-db-proxy --url=https://localhost:8080 --no-tls=true --port=4226 225 | ``` 226 | 227 | ## Use proxy locally 228 | 229 | To use it locally, download the binary according to your environment, and run it with proper parameters. The proxy 230 | run in and wait database connection. 231 | 232 | In another environment (your IDE, another shell), run your app or your database connexion on the `localhost:`. 233 | 234 | ## Use proxy in container 235 | 236 | If your environment allow you to start several container in the same time (Docker compose or Kubernetes Pods), you can 237 | add that container in the configuration `us-central1-docker.pkg.dev/gblaquiere-dev/public/serverless-db-proxy` 238 | 239 | If you use the proxy in your container, and you can't define several container in your deployment (like CLoud Run), you 240 | have to run in background the proxy while you run your app in the container. **The runtime environment must contain 241 | `/bin/bash` to run the startup script** 242 | 243 | The proposed way is a simple wrapping into a startup shell. That way works well but not propagate the 244 | signals (TERM or INT for instance to stop the application.). 245 | 246 | *To propagate the signals, you can use [dumb-init](https://github.com/Yelp/dumb-init) as used in 247 | [serverless-sql Dockerfile](https://github.com/guillaumeblaquiere/serverless-sql/tree/master/serverless-sql/Dockerfile)* 248 | 249 | ### Container parameters 250 | 251 | In the `startup.sh` file that start the proxy and wrap the app execution, you can customize the proxy execution 252 | parameters with environment variables 253 | 254 | * **URL**: *Equivalent to `--url` parameter.* Set the URL of the serverless database service to connect. If not set or 255 | set to empty string, the proxy exit gracefully. 256 | * **PORT**: *Equivalent to `--port` parameter.* The local port to listen. `3306` by default. 257 | * **NO_TLS**: *Equivalent to `--no-tls` parameter.* Deactivate the TLS support for HTTP/2 protocol (activate the clear 258 | text mode -> h2c). False by default, only for local tests 259 | 260 | ### Container layer mode 261 | 262 | To import the files directly from the official `serverless-db-proxy` container, you have to 263 | * Add Serverless db proxy container as layer in your`Dockerfile`, *for instance at the beginning* 264 | * Copy the `/serverless-db-proxy` binary from the proxy layer to the root path in your final layer 265 | * Copy the `/startup.sh` script from the proxy layer to the root path in your final layer 266 | * Define the `/startup.sh` as the entry point of the container 267 | * Define your app startup command as `CMD` in your final layer 268 | 269 | Similar to that 270 | 271 | ```Dockerfile 272 | # Import the Serverless db proxy as proxy layer 273 | FROM us-central1-docker.pkg.dev/gblaquiere-dev/public/serverless-db-proxy AS proxy 274 | 275 | # Build your container as usual 276 | FROM ... 277 | ... 278 | 279 | # At the end of your build 280 | # Add the startup script 281 | COPY --from=proxy /startup.sh / 282 | # Add the binary proxy 283 | COPY --from=proxy /serverless-db-proxy / 284 | 285 | # Define startup.sh as entrypoint 286 | ENTRYPOINT ["/startup.sh"] 287 | 288 | # Set your app entrypoint as CMD 289 | CMD ["/my-app"] 290 | ``` 291 | 292 | ### File download 293 | 294 | To download the files directly from the official `serverless-db-proxy` Cloud Storage, you have to 295 | * Download `/serverless-db-proxy` binary from Cloud Storage to the root path in your final layer 296 | * Copy the `/startup.sh` script from Cloud Storage to the root path in your final layer 297 | * Define the `/startup.sh` as the entry point of the container 298 | * Define your app startup command as `CMD` in your final layer 299 | 300 | Similar to that 301 | 302 | ```Dockerfile 303 | # Build your container as usual 304 | FROM ... 305 | ... 306 | 307 | # At the end of your build 308 | # Download the startup script 309 | RUN wget https://storage.googleapis.com/serverless-db-proxy/startup.sh -P / && chmod +x /startup.sh 310 | # Download the binary proxy 311 | RUN wget https://storage.googleapis.com/serverless-db-proxy/linux64/serverless-db-proxy -P / && chmod +x /serverless-db-proxy 312 | 313 | # Define startup.sh as entrypoint 314 | ENTRYPOINT ["/startup.sh"] 315 | 316 | # Set your app entrypoint as CMD 317 | CMD ["/my-app"] 318 | ``` 319 | 320 | # License 321 | 322 | This library is licensed under Apache 2.0.
