About

This project provisions Centos 7 based development environments with Ansible for running in Vagrant/VirtualBox. The Vagrantfile uses a base box from casparderksen/packer-kickstart-vagrant, but any Centos 7 image with Ansible pre-installed should work. See also this project for pre-packaging a development environment as Vagrant box (ideal when your corporate service management processes and internet policies fail to yield a satisfactory development environment).

The devbox.yml playbook installs the following software:

• Docker daemon
• Various Docker images
• Apache Maven
• OpenJDK-8 and 11 installation
• Scala
• Haskell
• R
• Python3
• Node and NPM
• Misc command line tools (git, jq, httpie, make, ...)

The local.yml playbook applies the following configuration (adapt variables to your environment):

• Angular CLI installation
• Docker daemon configured with private registry (for example Nexus3 pull through cache)
• Git client configuration
• Oracle Instantclient with tnsnames.ora configuration
• Maven, fully configured settings.xml for Nexus3 repository with encrypted password
• Node and NPM configured with Nexus as proxy
• Local CA trust stores for Linux and Java
• Configuration for CNTLM and running cntlmd daemon for corporate proxy integration

The graphical.yml playbook installs the following software:

• GNOME desktop

The minidcos.yml playbook installs the following software:

• miniDC/OS command line tool (minidcos)
• setup DC/OS in Docker cluster
• DC/OS command line tool (dcos)

The minikube.yml playbook installs the following software:

• Minikube command line tool (minikube)
• Kubernetes kubectl command line tool
• Minikube cluster on Docker (vmdriver=none)

The oracle.yml playbook installs the following software

• Oracle 12c RDBMS Docker image and example project
• Weblogic 12c Docker image

Usage

Clone casparderksen/packer-kickstart-vagrant and create an Ansible box. Alternatively, adapt the Vagrant file for using another box and installing Ansible.

Start the box, and enter it with SSH:

$ vagrant up
$ vagrant ssh

Adapt local.yml to yourn environment and needs. Then apply the confiuration as follows:

$ cd /vagrant/ansible
$ ansible-playbook local.yml

You will be prompter for full name, e-mail, user-id and password to configure Git, Maven, and CNTLM. Your password will be stored encrypted, but do keep the configured box and files private. Start a new shell to load configured environment and path settings.

When running Vagrant from Windows, the /vagrant/ansible folder is world-writable, causing Ansible to refuse work for security issues. To fix this, mount the ansible folder with restricted permissions Tip: the generated Maven settings.xml and settings-security.xml should be portable to your Windows box.

Oracle database in Docker

See Dependencies for creating Docker images for Oracle. Edit ansible/oracle.yml and remove docker-weblogic if you only need the database.

SSH into the box. To load the Docker image run:

$ cd /vagrant/ansible
$ ansible-playbook oracle.yml

To start the databse in the background:

$ cd ~/docker-oracle-example
$ make run

The first run will take a lot of time to create the database in a Docker volume. Type

$ make logs

to follow progress. Wait until the database is ready to use (abort watching the logs with Ctrl-C). To access the database via sqlplus:

$ sqlplus myschema/myschema@ORCLPDB1

The JDBC URL is jdbc:oracle:thin:@//localhost:1521/ORCLPDB1 (use a service connection).

Edit the scripts in docker-oracle-example/docker/setup to change the configured users. See local.yml for tnsnames.ora configuration.

miniDC/OS in Docker

SSH into the box and run:

$ cd /vagrant/ansible
$ ansible-playbook minidcos.yml

Wait for DC/OS to be ready. Go to http://localhost:8888 for accessing the DC/OS console.

Minikube in Docker

SSH into the box abd run:

$ cd /vagrant/ansible
$ ansible-playbook minikube.yml

Wait for the cluster to be ready. Run

$ sudo kubectl proxy --address='0.0.0.0' --disable-filter=true

to access the Kubernetes dashboard at http://localhost:8001/api/v1/namespaces/kube-system/services/http:kubernetes-dashboard:/proxy/.

Dependencies

CNTLM

Required file for CNTLM proxy:

files/cntlm/cntlm-0.92.3-1.x86_64.rpm

Download the CNTLM RPM package from http://cntlm.sourceforge.net.

Oracle 12c Database

Required file for Oracle database:

files/docker-oracle/oradb-12201-ee.tgz

Download the Oracle Database 12.2.0.1 Enterprise Edition installer from Oracle. Then build an Oracle container image as described in https://github.com/oracle/docker-images/tree/master/OracleDatabase/SingleInstance. Finally, save the docker image to file. Steps:

1. Clone the Oracle docker-images repo: git clone https://github.com/oracle/docker-images
2. Place linuxx64_12201_database.zip in docker-images/OracleDatabase/SingleInstance/dockerfiles/12.2.0.1.
3. Go to dockerfiles and run buildDockerImage.sh -v 12.2.0.1 -e
4. Save the image to file: docker save oracle/database:12.2.0.1-ee | gzip - > oradb-12201-ee.tgz

Oracle Weblogic

Required file for Weblogic:

files/docker-weblogic/weblogic-12213-dev.tgz

Download the Weblogic image from the Oracle Container Registry and save it to file as follows:

1. Login to the Oracle Container Registry: docker login container-registry.oracle.com
2. Pull the image: docker pull container-registry.oracle.com/middleware/weblogic:12.2.1.3-dev
3. Re-tag the image: docker tag container-registry.oracle.com/middleware/weblogic:12.2.1.3-dev oracle/weblogic:12.2.1.3-dev
4. Save the image to file: docker save oracle/weblogic:12.2.1.3-dev | gzip - > weblogic-12213-dev.tgz

Oracle Instantclient

Download the following files from https://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html.

instantclient/oracle-instantclient12.2-sqlplus-12.2.0.1.0-1.x86_64.rpm

Warning: Oracle licensing

Check your Oracle license! A developer license only allows deployment on a physical development PC. In general, Oracle does not allow soft partitioning and may require a license for the entire cluster on which an instance is deployed.
