# Jervis docker clients
These are the docker build files to create [Jervis][jervis] docker clients as
Jenkins build slaves.
# Build all operating system variants
A helpful build script is provided.
./build.sh
This will build the following containers:
- `jervis-alpine:latest`
- `jervis-centos7:latest`
- `jervis-centos7-android:latest`
- `jervis-centos7-dnd:latest`
- `jervis-ubuntu1604:latest`
- `jervis-ubuntu1804:latest`
Alternatively, to build a single variant, simply pass one or more directories as
arguments to `build.sh`. For example, to build `jervis-centos7-android` you
must first build the `jervis-centos7` base image.
./build.sh centos7 centos7-android
# Running containers
`docker run` is the typical method for running containers. To launch the
centos7 container:
docker run -it --rm jervis-centos7 /bin/bash
Other images can be launched with similar commands unless otherwise stated.
### Working with android emulators
The `jervis-centos7-android` image provides Android SDK tools, Android
platform-tools, and Android emulator. However, it does not install machine
images or set up hardware. That's left up to the developer running a build to
do in their build scripts. Here's an example of starting an emulator in the
background for running UI tests. For operating on most common Android phones,
`android-22` for ARMv7 is recommended.
docker run -it --rm jervis-centos7-android /bin/bash
From within the docker container:
yes | sdkmanager platform-tools emulator 'platforms;android-22' 'system-images;android-22;default;armeabi-v7a'
yes '' | avdmanager create avd --package 'system-images;android-22;default;armeabi-v7a' --abi armeabi-v7a --name android-phone
adb start-server
nohup emulator -avd android-phone -no-skin -no-window &
Now you're ready to run your tests.
./gradlew clean test connectedAndroidTest
### Working with docker in docker
The `jervis-centos7-dnd` image is provided for docker in docker operations.
Running the container with `--privileged` is required, however Docker CE has
done a lot of work to make sure `--privileged` is as safe as possible to run
docker in docker. The reason why `--privileged` is required is that docker
needs write access to `/sys/fs/cgroup` and other kernel APIs only available in
`--privileged` mode.
See security writeups:
- [Docker security][docker-security].
- [Docker run capabilies when `--privileged` option is
used][docker-capabilities].
Starting a docker container which runs docker in docker.
docker volume create docker-data
docker run -it --rm --privileged -v docker-data:/var/lib/docker jervis-centos7-dnd /bin/bash
All following commands occur within the docker container.
```bash
# start docker daemon with debug logging
sudo -i nohup dockerd -D &
# writes docker daemon logs to /root/nohup.out
docker pull centos:7
# run a docker container inside of the docker container
docker run -it --rm centos:7 /bin/bash
```
Things to note:
- docker daemon requires write access to a volume mounted on `/var/lib/docker`.
We did that by using docker volumes with `-v docker-data:/var/lib/docker`.
- **Do not** use the `docker-data` volume with more than one docker in docker
container. If you need to launch a second docker in docker container, then
create and mount a volume with a different name. Accessing `/var/lib/docker`
with multiple docker daemons will cause data corruption.
