+# Running Concourse on VIC
+
+
+### Step 1: Creating volumes for containers
+docker volume create --opt Capacity=1GB --name postgres
+docker volume create --opt Capacity=4GB --name concourse-keys
+docker volume create --opt Capacity=4GB --name worker-state
+
+
+### Step 2: Create docker network
+docker network create concourse-net
+
+
+### Step 3: Run the concourse-db container
+docker run --name concourse-db \
+  --net=concourse-net \
+  -h concourse-postgres \
+  -v postgres:/var/lib/postgresql/data \
+  -p 5432:5432 \
+  -e POSTGRES_USER=postgres \
+  -e POSTGRES_PASSWORD=vmware \
+  -e POSTGRES_DB=atc \
+  -d postgres
+
+### Step 4: Run the Concourse Container
+Change the external url in the command below to the fqdn/ip of your VCH. Also, change the DNS server to your environment's DNS server.
+docker run  --name concourse -h concourse \
+   -d -p 8080:8080 \
+   --net=concourse-net \
+   -v concourse-keys:/concourse-keys \
+   -v worker-state:/worker-state \
+   concourse/concourse quickstart \
+   --add-local-user=vic:vmware \
+   --main-team-local-user=vic \
+   --external-url=http://vch1.tpm.com:8080 \
+   --postgres-user=postgres \
+   --postgres-password=vmware \
+   --postgres-host=concourse-db \
+   --worker-garden-dns-server 8.8.8.8
+
+### Step 5: Navigate to concourse UI and login
+Navigate to the 'external-url' defined in step 4 and verify that UI is reachable. Download and install the 'fly' binary on a suitable machine.
+Login to concourse using vic/vmware from the UI.
