+## Fixturenet Eth
+
+* Stack: <https://git.vdb.to/cerc-io/fixturenet-eth-stacks>
+
+* Source repo: <https://git.vdb.to/cerc-io/lighthouse>
+
+* Target dir: `/srv/fixturenet-eth/fixturenet-eth-deployment`
+
+* Cleanup an existing deployment if required:
+
+  ```bash
+  cd /srv/fixturenet-eth
+
+  # Stop the deployment
+  laconic-so deployment --dir fixturenet-eth-deployment stop --delete-volumes
+
+  # Remove the deployment dir
+  sudo rm -rf fixturenet-eth-deployment
+  ```
+
+### Setup
+
+* Create a `fixturenet-eth` dir if not present already and cd into it
+
+  ```bash
+  mkdir /srv/fixturenet-eth
+
+  cd /srv/fixturenet-eth
+  ```
+
+* Clone the stack repo:
+
+  ```bash
+  laconic-so fetch-stack git.vdb.to/cerc-io/fixturenet-eth-stacks --pull
+  ```
+
+* Clone required repositories:
+
+  ```bash
+  laconic-so --stack ~/cerc/fixturenet-eth-stacks/stack-orchestrator/stacks/fixturenet-eth setup-repositories --pull
+
+  # If this throws an error as a result of being already checked out to a branch/tag in a repo, remove all repositories from that stack and re-run the command
+  # The repositories are located in $HOME/cerc by default
+  ```
+
+* Build the container images:
+
+  ```bash
+  # Remove any older foundry image with `latest` tag
+  docker rmi ghcr.io/foundry-rs/foundry:latest
+
+  laconic-so --stack ~/cerc/fixturenet-eth-stacks/stack-orchestrator/stacks/fixturenet-eth build-containers --force-rebuild
+
+  # If errors are thrown during build, old images used by this stack would have to be deleted
+  ```
+
+  * NOTE: this will take >10 mins depending on the specs of your machine, and **requires** 16GB of memory or greater.
+
+  * Remove any dangling Docker images (to clear up space):
+
+    ```bash
+    docker image prune
+    ```
+
+* Create spec files for deployments, which will map the stack's ports and volumes to the host:
+
+  ```bash
+  laconic-so --stack ~/cerc/fixturenet-eth-stacks/stack-orchestrator/stacks/fixturenet-eth deploy init --output fixturenet-eth-spec.yml
+  ```
+
+* Configure ports:
+  * `fixturenet-eth-spec.yml`
+
+    ```yml
+    ...
+    network:
+      ports:
+        fixturenet-eth-bootnode-geth:
+          - '9898:9898'
+          - '30303'
+        fixturenet-eth-geth-1:
+          - '8545:8545'
+          - '8546:8546'
+          - '40000'
+          - '6060'
+        fixturenet-eth-lighthouse-1:
+          - '8001'
+    ...
+    ```
+
+* Create deployments:
+  Once you've made any needed changes to the spec files, create deployments from them:
+
+  ```bash
+  laconic-so --stack ~/cerc/fixturenet-eth-stacks/stack-orchestrator/stacks/fixturenet-eth deploy create --spec-file fixturenet-eth-spec.yml --deployment-dir fixturenet-eth-deployment
+  ```
+
+* Env configuration:
+
+  ```bash
+  cat <<EOF > fixturenet-eth-deployment/config.env
+  CERC_ALLOW_UNPROTECTED_TXS=true
+  EOF
+  ```
+
+### Run
+
+* Start `fixturenet-eth-deployment` deployment:
+
+  ```bash
+  laconic-so deployment --dir fixturenet-eth-deployment start
+  ```
