Generating Custom Docker Images

Steps to build custom docker image for centos7, rhel7, centos6, rhel6, ubuntu16 base images.

For centos7:

Run the following command:
```
bdwb --baseimg  centos7
```
Once you execute this bdwb command, an new directory will be created (directory name will be the image name, e.g. centos7) with the following three files inside the directory:
- build.sh
- Makefile
- template directory that houses the Dockerfile.template and limits-90-nproc.conf files.
Set the following param before invoking the make command:
```
export CATALOG_BASE_IMG_VERSION=4.0
```
If make doesn't already exist in your environment, run:
```
yum install make
```
If you are using Docker 1.12 (docker --version), you must remove the '-f' argument in the following line of the build.sh file to avoid throwing errors:
```
docker tag -f $1 $2
```
Run the following command to execute the build:
```
make all
```
Once the image build is complete, you should see a Docker image locally (run docker images) with the name bluedata/centos7:latest for centos7.
You can now push this image of a remote repository or create a tar file and import it to other machines for creating other Docker images on top of this new base image. To tar the file, use the following command:
```
docker save -o <TAR_FILE_NAME> <IMAGE>:<TAG>
```

For rhel7:

Run the following command:
```
bdwb --baseimg  rhel7
```
Once you execute this bdwb command, an new directory will be created (directory name will be the image name, e.g. rhel7) with the following three files inside the directory:
- build.sh
- Makefile
- template directory that houses the Dockerfile.template and limits-90-nproc.conf files.
Set the following param before invoking the make command:
```
export CATALOG_BASE_IMG_VERSION=4.0
```

Set RHEL username and password:

export RHEL_USERNAME=<username>

export RHEL_PASSWORD=<password>

If make doesn't already exist in your environment, run:
```
yum install make
```
If you are using Docker 1.12 (docker --version), you must remove the '-f' argument in the following line of the build.sh file to avoid throwing errors:
```
docker tag -f $1 $2
```
Run the following command to execute the build:
```
make all
```
Once the image build is complete, you should see a Docker image locally (run docker images) with the name bluedata/rhel7:latest for rhel7.
You can now push this image of a remote repository or create a tar file and import it to other machines for creating other Docker images on top of this new base image. To tar the file, use the following command:
```
docker save -o <TAR_FILE_NAME> <IMAGE>:<TAG>
```

For centos6:

Run the following command:
```
bdwb --baseimg  centos6
```
Once you execute this bdwb command, an new directory will be created (directory name will be the image name, e.g. centos6) with the following three files inside the directory:
- build.sh
- Makefile
- template directory that houses the Dockerfile.template and limits-90-nproc.conf files.
Set the following param before invoking the make command:
```
export CATALOG_BASE_IMG_VERSION=2.1
```
If make doesn't already exist in your environment, run:
```
yum install make
```
If you are using Docker 1.12 (docker --version), you must remove the '-f' argument in the following line of the build.sh file to avoid throwing errors:
```
docker tag -f $1 $2
```
Run the following command to execute the build:
```
make all
```
Once the image build is complete, you should see a Docker image locally (run docker images) with the name bluedata/centos6:latest for centos6.
You can now push this image of a remote repository or create a tar file and import it to other machines for creating other Docker images on top of this new base image. To tar the file, use the following command:
```
docker save -o <TAR_FILE_NAME> <IMAGE>:<TAG>
```

For rhel6:

Run the following command:
```
bdwb --baseimg  rhel6
```
Once you execute this bdwb command, an new directory will be created (directory name will be the image name, e.g. rhel6) with the following three files inside the directory:
- build.sh
- Makefile
- template directory that houses the Dockerfile.template and limits-90-nproc.conf files.
Set the following param before invoking the make command:
```
export CATALOG_BASE_IMG_VERSION=2.1
```

Set RHEL username and password:

export RHEL_USERNAME=<username>

export RHEL_PASSWORD=<password>

If make doesn't already exist in your environment, run:
```
yum install make
```
If you are using Docker 1.12 (docker --version), you must remove the '-f' argument in the following line of the build.sh file to avoid throwing errors:
```
docker tag -f $1 $2
```
Run the following command to execute the build:
```
make all
```
Once the image build is complete, you should see a Docker image locally (run docker images) with the name bluedata/rhel6:latest for rhel6.
You can now push this image of a remote repository or create a tar file and import it to other machines for creating other Docker images on top of this new base image. To tar the file, use the following command:
```
docker save -o <TAR_FILE_NAME> <IMAGE>:<TAG>
```

For Ubuntu16:

Run the following command:
```
bdwb --baseimg  ubuntu16
```
Once you run this, an new directory will be created (directory name will be the image name, e.g. ubuntu16) with the following two files inside the directory:
- Makefile
- template directory that houses the Dockerfile.template and limits-90-nproc.conf files.
Set the following param before invoking the make command:
```
export CATALOG_BASE_IMG_VERSION=3.0
```
If make doesn't already exist in your environment, run:
```
yum install make
```
If you are using Docker 1.12 (docker --version), you must remove the '-f' argument in the following line of the Makefile to avoid throwing errors:
```
docker tag -f $1 $2
```
Run the following command to execute the build:
```
make all
```
Once the image build is complete, you should see a Docker image locally (run docker images) with the name bluedata/ubuntu16:latest for ubuntu16.
You can now push this image of a remote repository or create a tar file and import it to other machines for creating other Docker images on top of this new base image. To tar the file, use the following command:
```
docker save -o <TAR_FILE_NAME> <IMAGE>:<TAG>
```

NOTES:

If you are planning to make changes to the existing Dockerfile with versions, etc., some of the EPIC features may not work and could potentially cause issues.
If you are building base centos/rhel/ubuntu image on Docker 1.7, it will work with higher versions of Docker (i.e. Docker 1.12), but the opposite is not true.
User Authentication is not currently available for the Ubuntu image, but will be made available in a later App Workbench release.
