+When starting a container running ipfs for the first time with an empty data directory, it will call `ipfs init` to initialize configuration files and generate a new keypair. At this time, you can choose which profile to apply using the `IPFS_PROFILE` environment variable:
+
+    docker run -d --name ipfs_host -e IPFS_PROFILE=server -v $ipfs_staging:/export -v $ipfs_data:/data/ipfs -p 4001:4001 -p 127.0.0.1:8080:8080 -p 127.0.0.1:5001:5001 ipfs/go-ipfs:latest

 ### Troubleshooting
 
 If you have previously installed IPFS before and you are running into problems getting a newer version to work, try deleting (or backing up somewhere else) your IPFS config directory (~/.ipfs by default) and rerunning `ipfs init`. This will reinitialize the config file to its defaults and clear out the local datastore of any bad entries.
