 ## v0.4.28
 
+FEATURE: A minimal Docker Compose project for self-hosting a zrok instance and [accompanying Docker guide](https://docs.zrok.io/docs/guides/self-hosting/docker) for more information.
+
 CHANGE: the container images run as "ziggy" (UID 2171) instead of the generic restricted user "nobody" (UID 65534). This reduces the risk of unexpected file permissions when binding the Docker host's filesystem to a zrok container.
 
 CHANGE: the Docker sharing guides were simplified and expanded

+
+## Docker Quickstart
+
+### DNS Configuration
+
+The quickstart makes these assumptions about your global DNS configuration.
+
+1. You have designated A DNS zone for zrok, e.g. `example.com` or `share.example.com` and created (and delegated, if necessary) the zone on your DNS provider's platform.
+1. A wildcard record exists for the IP address where the zrok instance will run, e.g. if your DNS zone is `share.example.com`, then your wildcard record is `*.share.example.com`.
+1. A Caddy DNS plugin is available for your DNS provider (see [github.com/caddy-dns](https://github.com/caddy-dns))
+1. You have created an API token in your DNS provider's platform and the token has permission to create DNS records in the DNS zone.
+
+### Create a Docker Compose Project
+
+Create a working directory on your Docker host and save these Docker Compose project files. A OpenZiti network is provided by the "quickstart" container and is managed exclusively by zrok.
+
+```bash
+wget https://get.openziti.io/dock/all-in-one/compose.yml
+wget -O ./compose.override.yml https://get.openziti.io/zrok-quick/compose.yml
+```
+
+The project files provide these service containers.
+
+- `compose.yml`
+  - `quickstart`
+- `compose.override.yml`
+  - `zrok-controller`
+  - `zrok-frontend`
+  - `caddy`
+
+### Configure the Docker Compose Project Environment
+
+Create an `.env` file in the working directory.
+
+```bash title=".env required"
+ZROK_DNS_ZONE=share.example.com
+
+# this must == ziti.${ZROK_DNS_ZONE}
+ZITI_CTRL_ADVERTISED_ADDRESS=ziti.share.example.com
+ZITI_PWD=zitiadminpw
+
+ZROK_ADMIN_TOKEN=zroktoken
+ZROK_USER_PWD=zrokuserpw
+
+CADDY_DNS_PLUGIN=cloudflare
+CADDY_DNS_PLUGIN_TOKEN=abcd1234
+CADDY_ACME_EMAIL=me@example.com
+```
+
+```bash title=".env options"
+ZITI_CTRL_ADVERTISED_PORT=1280
+ZITI_ROUTER_PORT=3022
+
+# configure oauth for public shares
+ZROK_OAUTH_HASH_KEY=oauthhashkeysecret
+ZROK_OAUTH_GITHUB_CLIENT_ID=abcd1234
+ZROK_OAUTH_GITHUB_CLIENT_SECRET=abcd1234
+ZROK_OAUTH_GOOGLE_CLIENT_ID=abcd1234
+ZROK_OAUTH_GOOGLE_CLIENT_SECRET=abcd1234
+
+# use the staging API until you're sure everything is working to avoid hitting the main CA's rate limit
+CADDY_ACME_API=https://acme-staging-v02.api.letsencrypt.org/directory
+```
+
+### Start the Docker Compose Project
+
+1. Start the ziti network. This runs `ziti edge quickstart` ([link to readme](https://github.com/openziti/ziti/tree/main/quickstart/docker/all-in-one#readme)).
+
+    ```bash
+    docker compose --profile ziti up --detach
+    ```
+
+1. Start the zrok instance.
+
+    The container images for zrok (including caddy) are built in this step. This provides a simple configuration to get started. You can modify the templates named like `*.envsubst` or mount a customized configuration file to mask the one that was built in.
+
+    ```bash
+    docker compose --profile zrok up --build --detach
+    ```
+
+### Set up a User Account
+
+This step creates a user account. You will log in to the zrok web console with the account password created in this step. The CADDY_ACME_EMAIL and ZROK_USER_PWD variables are set in the `.env` file. You can create more user accounts the same way by substituting a different email and password.
+
+```bash
+docker compose exec zrok-controller bash -xc 'zrok admin create account /etc/zrok-controller/config.yml ${CADDY_ACME_EMAIL} ${ZROK_USER_PWD}'
+```
+
+```buttonless title="Example output"
++ zrok admin create account /etc/zrok-controller/config.yml me@example.com zrokuserpw
+[   0.000]    INFO zrok/controller/store.Open: database connected
+[   0.002]    INFO zrok/controller/store.(*Store).migrate: applied 0 migrations
+heMqncCyxZcx
+```
+
+### Enable the User Environment
+
+You must enable each device environment with the account token obtained when the account was created. This is separate from the account password that's used to log in to the web console.
+
+Follow [the getting started guide](/docs/getting-started#installing-the-zrok-command) to install the zrok CLI on some device and enable a zrok environment.
+
+1. Enable an environment on this device with the account token from the previous step.
+
+    ```bash
+    zrok enable heMqncCyxZcx
+    ```
+
+1. Configure the environment with the zrok API. Substitute the API endpoint with the one you're using, e.g. `https://zrok.${ZROK_DNS_ZONE}`.
+
+    ```bash
+    zrok config set apiEndpoint https://zrok.share.example.com
+    ```
+
+### Firewall Configuration
+
+The `quickstart` and `caddy` containers publish ports to all devices that use zrok shares. The `zrok-controller` and `zrok-frontend` containers expose ports only to the `caddy` container and the Docker host's loopback interface.
+
+#### Required
+
+1. `443/tcp` - reverse proxy handles HTTPS requests for zrok API, OAuth, and public shares (published by container `caddy`)
+1. `1280/tcp` - ziti ctrl plane (published by container `quickstart`)
+1. `3022/tcp` - ziti data plane (published by container `quickstart`)
+
+#### Optional
+
+1. `80/tcp` - reverse proxy redirects non-HTTPS requests to `443/tcp` (published by container `caddy`)
+<!-- 1. 443/udp used by Caddy for HTTP/3 QUIC protocol (published by container `caddy`) -->
+
+### Troubleshooting
+
+1. Check the ziti and zrok logs.
+
+    You can substitute the service container name of each to check their logs individually: `quickstart` (ziti container), `zrok-controller`, `zrok-frontend`.
+
+    ```bash
+    docker compose logs zrok-controller
+    ```
+
+1. Check the caddy logs.
+
+    It can take a few minutes for Caddy to obtain the wildcard certificate. You can check the logs to see if there were any errors completing the DNS challenge which involves using the Caddy DNS plugin to create a TXT record in your DNS zone. This leverages the API token you provided in the `.env` file, which must have permission to create DNS records in the zrok DNS zone.
+
+    ```bash
+    docker compose logs caddy
+    ```
+
+1. `zrok enable` fails certificate verification: ensure you are not using the staging API for Let's Encrypt.
+
+    If you are using the staging API, you will see an error about the API certificate when you use the zrok CLI. You can switch to the production API by removing the overriding assignment of the `CADDY_ACME_API` variable.
+
+    ```buttonless title="Example output"
+    there was a problem enabling your environment!
+    you are trying to use the zrok service at: https://zrok.share.example.com
+    you can change your zrok service endpoint using this command:
+
+    $ zrok config set apiEndpoint <newEndpoint>
+
+    (where newEndpoint is something like: https://some.zrok.io)
+    [ERROR]: error creating service client (error getting version from api endpoint 'https://zrok.share.example.com': Get "https://zrok.share.example.com/api/v1/version": tls: failed to verify certificate: x509: certificate signed by unknown authority: Get "https://zrok.share.example.com/api/v1/version": tls: failed to verify certificate: x509: certificate signed by unknown authority)
+    ```
+
+1. Validate the Caddyfile.
+
+    ```bash
+    docker compose exec caddy caddy validate --config /etc/caddy/Caddyfile
+    ```
+
+1. Verify the correct DNS provider module was built-in to Caddy.
+
+    ```bash
+    docker compose exec caddy caddy list-modules | grep dns.providers
+    ```
+
+    ```buttonless title="Example output"
+    dns.providers.cloudflare
+    ```
+
+1. Verify certificates.
+
+    You can check the certificates that Caddy has obtained.
+
+    ```bash
+    docker compose exec caddy caddy list-certificates
+    ```
+
+1. Use the Caddy admin API.
+
+    You can use the Caddy admin API to check the status of the Caddy instance. The admin API is available on port `2019/tcp` inside the Docker compose project. You can modify `compose.override.yml` to publish the port if you want to access the admin API from the Docker host or elsewhere.
+
+    ```bash
+    docker compose exec caddy curl http://localhost:2019/config/ | jq
+    ```

 The id of the frontend was emitted earlier in by the zrok controller when we ran the bootstrap command. If you don't have that log message the you can find the id again with the `ziti` CLI like this:
 
 ```bash
-# initialize the Ziti quickstart env

-source ~/.ziti/quickstart/$(hostname -s)/$(hostname -s).env
+ziti edge login localhost:1280 -u admin -p XO0xHp75uuyeireO2xmmVlK91T7B9fpD
