Subject: Update Dockerfile-alpine (#166)
X-Git-Url: http://git.prime8.dev/?a=commitdiff_plain;h=0f23415e980a8b44f3cb2b2ba8db17f1737d25a7;p=ttyd.git

Update Dockerfile-alpine (#166)

* Dockerfile-alpine: update Alpine to v3.9

ttyd in Alpine v3.6 repository is v1.3.2, in Alpine v3.9, it's v1.4.2

* Dockerfile-alpine: simplify package installation

Use `--no-cache` to avoid the need to use `--update` and remove
`/var/cache/apk/*` manually
