Installation of Apache Ant 1.10.x and docker-ce 17.x on CentOS7 Jenkins Master and Slaves
This Requires that JRE is installed. Please note that the Ant 1.1o.x requires that JRE 1.8 to be installed.
This will ensure that the Jenkins master identically have the Docker and the Ant installations so that the builds that need ant and docker can be identically run from the Jenkins master as well as Jenkins Slave servers.
Sources:
- Also JAVA_HOME is to be set to the path where JRE is installed.
- Latest versions of Apache ant are available from http://ant.apache.org/bindownload.cgi
- Ant 1.10.x requires the Java8 JRE.
- we have installed the Java8 from oracle for Linux as we are running these on the CentOS 7 server.
Please note that this is an RPM based installed of 64 Bit 1.8.0 update 152 from here

Installation of Ant 1.10.x
Download the ANT binaries
wget http://redrockdigimark.com/apachemirror/ant/binaries/apache-ant-1.10.1-bin.tar.gz
Extract the Binaries to a folder, here the same is extracted into /opt
tar zxvf apache-ant-1.10.1-bin.tar.gz -C /opt
See the extracted folder
[root@jenkinsmaster apache-ant-1.10.1]# ls -la /opt
total 8

[root@jenkinsmaster apache-ant-1.10.1]#
This is optional if the ANT_HOME and PATH as shown below are set. This creates the soft link for the ant command in the extracted files to the /usr/bin/ant
[root@jenkinsmaster bin]# ln -s /opt/apache-ant-1.10.1/bin/ant /usr/bin/ant

Append these lines to the /etc/profile or BASH Profile or BASHRC to set the ANT and JAVA environment variables
Here we had added these lines to the /etc/profile
export ANT_HOME=/opt/apache-ant-1.10.1
export PATH=$PATH:$ANT_HOME/bin
export JAVA_HOME=/usr/java/jdk1.8.0_152
export PATH=$PATH:$JAVA_HOME/bin
Here we had added these lines to the /etc/profile
export ANT_HOME=/opt/apache-ant-1.10.1
Ensure that these are working

Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash
