## Make your OpenSSH fly on Alpine
|
|
|
|
### Overview
|
|
Use this Dockerfile / -image to start a sshd-server upon a lightweight Alpine container.
|
|
|
|
### Features
|
|
* Always installs the latest OpenSSH-Version available for Alpine
|
|
* Password of "root"-user can be changed when starting the container using --env
|
|
|
|
### Basic Usage
|
|
#### Authentication by password
|
|
```
|
|
$ docker run --rm \
|
|
--publish=1337:22 \
|
|
--env ROOT_PASSWORD=MyRootPW123 \
|
|
hermsi/alpine-sshd
|
|
```
|
|
|
|
After the container is up you are able to ssh in it as root with the in --env provided password for "root"-user.
|
|
```
|
|
$ ssh root@mydomain.tld -p 1337
|
|
```
|
|
#### Authentication by ssh-keypair
|
|
```
|
|
$ docker run --rm \
|
|
--publish=1337:22 \
|
|
--env KEYPAIR_LOGIN=true \
|
|
--volume /path/to/authorized_keys:/root/.ssh/authorized_keys \
|
|
hermsi/alpine-sshd
|
|
```
|
|
After the container is up you are able to ssh in it as root by a keypair which matches the provided public-key in authorized_keys for "root"-user.
|
|
```
|
|
$ ssh root@mydomain.tld -p 1337 -i /path/to/private_key
|
|
```
|
|
### Use with docker-compose
|
|
I built this image in order to use it along with a nginx and fpm-php container for transferring files via sftp.
