docker practice use jenkins image


If you want to learn from scratch Docker, Take a look at this series of articles !

https://www.cnblogs.com/poloyy/category/1870863.html

 

install Docker

Refer to my article directly :https://www.cnblogs.com/poloyy/p/13921450.html

 

download Jenkins Mirror image

Search for jenkins Mirror image

docker search jenkins

Focus on the first three

  1. The first is the official mirror image , But the version is old , Not recommended
  2. Although it's not the official mirror image , however jenkins The version of will follow jenkins The official version , That is to say, it will keep the mirror image down jenkins The version is the latest , recommend , I also use this
  3. The third image is Chinese jenkins Mirror image , But the mirror system is not familiar to us centos、ubuntu、Debian  etc. , It is Alpine, It's not common to install dependent libraries , Not recommended

 

download jenkins Mirror image

docker pull jenkins/jenkins

This will download the latest version of jenkins Mirror image

 

View local image

docker images 

 

establish Jenkins Containers

Create a directory under the host

Used to mount the directory

mkdir -p /var/jenkins_node

 

Give the mount directory the highest permission

Readable, writable, and executable

chmod -R 777 /var/jenkins_node

 

Create and launch jenkins Containers

  • -d: Guardian mode
  • -uroot: Use root Identity into the container , It is recommended to add , Avoid permission errors when executing certain commands in the container
  • -p: host 80 Of the port mapping container 8080 port , Later visit jenkins Direct access to the host ip That's it , No need to add 8080 port
  • -v: Directory mapping
  • --name: Customize a container name
  • Use the one recommended above jenkins/jenkins Mirror image
docker run -d -uroot -p 80:8080 --name jenkins1 -v /var/jenkins_node:/var/jenkins_home jenkins/jenkins

 

See if the container is running

docker ps

 

Get into jenkins Containers CLI Interface

docker exec -it -uroot jenkins1 bash

You can also specify root Identity into the container

 

Lead to

# Get the latest packages
apt-get update
# Upgrade installed packages
apt-get upgrade
# Install in advance , For the next configuration operation
apt-get -y install gcc automake autoconf libtool make
apt-get -y install make*
apt-get -y install zlib*
apt-get -y install openssl libssl-dev
apt-get install sudo

 

install Python Environmental Science

download python

cd /usr/local/src
wget https://www.python.org/ftp/python/3.6.8/Python-3.6.8.tgz
tar -zxvf Python-3.6.8.tgz
mv Python-3.6.8 py3.6
cd py3.6

 

make Compilation and installation

stay  /usr/local/src/py3.6  Execute the following command in the installation directory

./configure --prefix=/var/jenkins_home/py3.6
make && make install

 

Add soft link

add to python3 Soft link

ln -s /usr/local/src/py3.6/bin/python3.6 /usr/bin/python3

 

add to pip3 Soft link

ln -s /usr/local/src/py3.6/bin/pip3 /usr/bin/pip3

If you have some, just ignore it

 

verification python3 Environmental Science

knock python3 and pip3 The result of the figure below is normal

 

Install the library required for the project

First

Need to be in python The project generates a requirement.txt, The specific tutorial can be seen in

https://www.cnblogs.com/poloyy/p/13953232.html

 

then

  • take requirement.txt Upload to the host
  • Copy from host to container  docker cp requirement.txt jenkins1:/usr/local/src 

 

Finally, install the required libraries for the project

pip3 install -r requirements.txt

 

install Allure Environmental Science

Download from the official website allure package

https://github.com/allure-framework/allure2/releases

Just choose the latest version , Or pick your own version

 

Transfer the compressed package into the container

  1. First upload the package to the host
  2. Then copy from the host to the container
docker cp allure-commandline-2.13.6.zip jenkins1:/usr/local/src

 

Unzip the package

unzip allure-commandline-2.13.6.zip

 

Give the highest permission to all contents of the folder

mv allure-2.13.6 allure
chmod -R 777 allure

 

To configure allure and py environment variable

cat >> /etc/profile << "EOF"
export PATH=/usr/local/src/allure/bin:$PATH
export PATH=/usr/local/src/py3.6/bin:$PATH
EOF

Remember to return one by one , Copy and paste, or just copy and paste

 

Update environment variable configuration file

source /etc/profile

 

Verify environment variables

allure --version
python3 --version

 

 

To configure JDK environment variable

View the current system configured environment variables

export

Here you can see many environment variables that come with the container itself

  • Jenkins Version of
  • JDK Installation path for

 

To configure JDK environment variable

cat >> /etc/profile << "EOF"
export PATH=$JAVA_HOME/bin:$PATH
EOF

 

Update environment variable configuration file

source /etc/profile
