#### Private swarms inside Docker

It is possible to initialize the container with a swarm key file (`/data/ipfs/swarm.key`) using the variables `IPFS_SWARM_KEY` and `IPFS_SWARM_KEY_FILE`. The `IPFS_SWARM_KEY` creates `swarm.key` with the contents of the variable itself, whilst `IPFS_SWARM_KEY_FILE` copies the key from a path stored in the variable. The `IPFS_SWARM_KEY_FILE` **overwrites** the key generated by `IPFS_SWARM_KEY`.

#### Key rotation inside Docker

If needed, it is possible to do key rotation in an ephemeral container that is temporarily executing against a volume that is mounted under `/data/ipfs`:

```sh
# given container named 'ipfs-test' that persists repo at /path/to/persisted/.ipfs
$ docker run -d --name ipfs-test -v /path/to/persisted/.ipfs:/data/ipfs ipfs/go-ipfs:v0.7.0
$ docker stop ipfs-test

# key rotation works like this (old key saved under 'old-self')
$ docker run --rm -it -v /path/to/persisted/.ipfs:/data/ipfs ipfs/go-ipfs:v0.7.0 key rotate -o old-self -t ed25519
$ docker start ipfs-test # will start with the new key
```

### 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.
