Continuous Integration with GitLab

Transcript

1. CONTINUOUS INTEGRATION WITH GITLAB IVAN NEMYTCHENKO, DEVELOPER ADVOCATE
2. MODERN SOFTWARE DEVELOPMENT PROCESS IS SPREAD ACROSS MANY TOOLS
3. Travis - GitHub - Trello - Slack
4. Bitbucket - Semaphore - Pivotal Tracker - HipChat
5. Jenkins - GitLab - Jira
17. CATGREP SOPHISTICATED TECHNOLOGIES INC. > file1.txt > file2.txt
18. REQUIREMENT #1 CONCATENATION RESULT SHOULD CONTAIN "HELLO WORLD"
19. cat file1.txt file2.txt | grep -q "Hello world"
21. RUN OUR FIRST TEST INSIDE CI
22. .gitlab-ci.yml
23. test: script: cat file1.txt file2.txt | grep -q 'Hello world'
26. REQUIREMENT #2 PACKAGE CODE BEFORE SENDING IT TO CUSTOMER
27. test: script: cat file1.txt file2.txt | grep -q 'Hello world' package: script: cat file1.txt file2.txt | gzip > package.gz
29. MAKE RESULTS OF YOUR BUILD DOWNLOADABLE
30. test: script: cat file1.txt file2.txt | grep -q 'Hello world' package: script: cat file1.txt file2.txt | gzip > packaged.gz artifacts: paths: - packaged.gz
32. RUN JOBS SEQUENTIALLY
33. stages: - test - package test: stage: test script: cat file1.txt file2.txt | grep -q 'Hello world' package: stage: package script: cat file1.txt file2.txt | gzip > packaged.gz artifacts: paths: - packaged.gz
34. SPEEDING UP THE BUILD
35. #1: DUPLICATION
36. stages: - compile - test - package compile: stage: compile script: cat file1.txt file2.txt > compiled.txt artifacts: paths: - compiled.txt test: stage: test script: cat compiled.txt | grep -q 'Hello world' package: stage: package script: cat compiled.txt | gzip > packaged.gz artifacts: paths: - packaged.gz
37. #2: RUBY 2.1 ????
38. LEARNING WHAT DOCKER IMAGE TO USE
39. image: alpine
40. image: alpine stages: - compile - test - package compile: ... test: ...
42. > defined 3 stages > pass files between stages > downloadable artifacts > optimized execution time
43. REQUIREMENT #3 ISO INSTEAD OF GZIP
44. DEALING WITH COMPLEX SCENARIOS
46. image: alpine stages: - compile - test - package compile: ... test: ... pack-gz: stage: package script: cat compiled.txt | gzip > packaged.gz artifacts: paths: - packaged.gz pack-iso: stage: package script: - mkisofs -o ./packaged.iso ./compiled.txt artifacts: paths: - packaged.iso
48. DEALING WITH MISSING SOFTWARE/PACKAGES
49. INSTALL PACKAGE IN ALPINE LINUX apk add -U cdrkit
50. script: - apk add -U cdrkit - mkisofs -o ./packaged.iso ./compiled.txt
51. pack-iso: stage: package before_script: - apk add -U cdrkit script: - mkisofs -o ./packaged.iso ./compiled.txt artifacts: paths: - packaged.iso
54. GITLAB REQUIREMENT #4 PUBLISH A SMALL WEBSITE WITH OUR PACKAGES
55. HTML + PACKAGES → AMAZON S3
56. aws s3 cp ./ s3://yourbucket/ --recursive
59. FIRST AUTOMATED DEPLOYMENT
60. > awscli can be installed using pip > pip goes together with python
61. s3: image: python:latest stage: deploy script: - pip install awscli - aws s3 cp ./ s3://yourbucket/ --recursive
62. AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY
63. variables: AWS_ACCESS_KEY_ID: "AKIAIOSFODNN7EXAMPLE" AWS_SECRET_ACCESS_KEY: “wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY” s3: image: python:latest stage: deploy script: - pip install awscli - aws s3 cp ./ s3://yourbucket/ --recursive
64. KEEPING SECRET THINGS SECRET
65. SETTINGS --> VARIABLES
66. s3: image: python:latest stage: deploy script: - pip install awscli - aws s3 cp ./ s3://yourbucket/ --recursive
67. So far so good:
68. REQUIREMENT #5 MORE THAN ONE DEVELOPER ON THE PROJECT
69. s3: image: python:latest stage: deploy script: - pip install awscli - aws s3 cp ./ s3://yourbucket/ --recursive only: - master
71. REQUIREMENT #6 WE NEED A SEPARATE PLACE FOR TESTING
72. GITLAB PAGES
73. HOST WEBSITES ON GITLAB PAGES > your job should be named "pages" > put your files into "public" folder > specify "artifacts" section with this "public" folder
74. HOST WEBSITES ON GITLAB PAGES > your job should be named "pages" > put your files into "public" folder > specify "artifacts" section with this "public" folder HTTP://<USERNAME>.GITLAB.IO/<PROJECTNAME>
75. pages: stage: deploy image: alpine:latest script: - mkdir -p ./public && cp ./*.* ./public/ artifacts: paths: - public except: - master
76. s3: image: python:latest stage: deploy script: - pip install awscli - aws s3 cp ./ s3://yourbucket/ --recursive only: - master pages: image: alpine:latest stage: deploy script: - mkdir -p ./public && cp ./*.* ./public/ artifacts: paths: - public except: - master
80. INTRODUCING ENVIRONMENTS
81. s3: environment: production image: python:latest stage: deploy script: - pip install awscli - aws s3 cp ./ s3://$S3_BUCKET_NAME/ --recursive only: - master pages: image: alpine:latest environment: staging stage: deploy script: - mkdir -p ./public && cp ./*.* ./public/ artifacts: paths: - public except: - master
85. REQUIREMENT #7 DO NOT MESS UP PRODUCTION
86. SWITCHING TO MANUAL DEPLOYMENT
87. s3: image: python:latest stage: deploy script: - pip install awscli - aws s3 cp ./ s3://yourbucket/ --recursive only: - master when: manual
88. SUMMARY 1. Deployment is just a set of commands 2. You need to provide secret keys 3. You specify where which branches should go to 4. GitLab conserves the history of deployments 5. You can enable manual deployment
