## Docker Hub
The images are automatically rebuilt on new GIT tags or pushes to the master branch:
`Dockerfile.centos7-nmstate` by https://cloud.docker.com/u/nmstate/repository/docker/nmstate/centos7-nmstate
`Dockerfile.centos7-nmstate-base` by https://cloud.docker.com/u/nmstate/repository/docker/nmstate/centos7-nmstate-base
The base image contains a common base that is used both for the development
image and for the distributed image.
Configuration (here for `centos7-nmstate-base`, the other build just specifies
a different container spec (Dockerfile location):
Source repo: nmstate/nmstate
Autotest: Off
Repository Links: Off
Build rules:
Branch:
Source:master
Docker Tag:latest
Dockerfile location:Dockerfile.centos7-nmstate-base
Build Context:/packaging
Autobuild:on
Build Caching:off
Tag:
Source: /^v[0-9.]+$/
Docker Tag:{sourceref}
Dockerfile location:Dockerfile.centos7-nmstate-base
Build Context:/packaging
Autobuild:on
Build Caching:off
## Manual Building
The Nmstate user image builds the master master branch by default. To specify a
different commit or tag, specify the `SOURCE_COMMIT` build argument:
```shell
sudo docker build --no-cache --build-arg SOURCE_COMMIT=v0.0.4 -t nmstate/centos7-nmstate -f Dockerfile.centos7-nmstate .
```
