GoCD agent images used for building GoCD

Images built:

• gocddev/gocd-dev-build:dind-<github_tag>
• gocddev/gocd-dev-build:centos-9-<github_tag>
• gocddev/gocd-dev-build:ubuntu-24-04-<github_tag>
• gocddev/gocd-dev-build:windows2022-<github_tag>

To build a new version of the images, push a new version tag to this repository.

Build an image locally

• docker build . --pull -t gocddev/gocd-dev-build:dind-SNAPSHOT -f dind.Dockerfile
• docker build . --pull -t gocddev/gocd-dev-build:centos-9-SNAPSHOT -f centos.Dockerfile
• docker build . --pull -t gocddev/gocd-dev-build:ubuntu-24-04-SNAPSHOT -f ubuntu.Dockerfile
• docker build . --pull -t gocddev/gocd-dev-build:windows2022-SNAPSHOT -f windowsservercore.Dockerfile

Publish

To publish a new image - add a new tag to the repository. The workflow will be triggered which will publish the image to docker hub.

gocd-oss-cookbooks's Issues

Create Ubuntu 22.04 build

Currently this isn't possible because we install Ruby 2.7.5 which doesn't have requirements met on Ubuntu 22.04 for building via ruby-build: rbenv/ruby-build#1940

Seem to need to either

• do some hijinx to get OpenSSL v1 onto Ubunto 22.04
• OR migrate to Ruby 3.1+ (which might be a better way forward since needs to be done eventually)

Missing mime types

Not entirely sure where to do this in this repo. So, opening an issue instead.

When aws s3 sync is used (as in the documentation pipeline), it tries to guess the mime-type to use for a file. This happens in aws-cli, here for the version we have in gocddev/gocd-dev-build:centos-6-v2.0.27.

However, the file /etc/mime.types does not exist. So, this causes aws s3 sync to use a default content-type of binary/octet-stream for files such as SVG files, causing S3 to serve them as such. Browsers will refuse to display such SVG files.

$ python -c 'import mimetypes; print(mimetypes.knownfiles); print("\nMime type of test.svg is: " + str(mimetypes.guess_type("test.svg")[0]))'

['/etc/mime.types', '/etc/httpd/mime.types', '/etc/httpd/conf/mime.types', '/etc/apache/mime.types', '/etc/apache2/mime.types', '/usr/local/etc/httpd/conf/mime.types', '/usr/local/lib/netscape/mime.types', '/usr/local/etc/httpd/conf/mime.types', '/usr/local/etc/mime.types']

Mime type of test.svg is: None

$ sudo yum install -y mailcap
...

$ python -c 'import mimetypes; print(mimetypes.knownfiles); print("\nMime type of test.svg is: " + str(mimetypes.guess_type("test.svg")[0]))'

['/etc/mime.types', '/etc/httpd/mime.types', '/etc/httpd/conf/mime.types', '/etc/apache/mime.types', '/etc/apache2/mime.types', '/usr/local/etc/httpd/conf/mime.types', '/usr/local/lib/netscape/mime.types', '/usr/local/etc/httpd/conf/mime.types', '/usr/local/etc/mime.types']

Mime type of test.svg is: image/svg+xml

Summary:

We need to install the mailcap package, at least for the centos-6 and centos-7 images. Maybe it should be added somewhere here?

CentOS 7 build is broken

Running docker image build for centos 7:

docker build . -t gocddev/gocd-dev-build:centos7 -f Dockerfile.centos7

Results in following errors:

I tracked down that setup of SCL repo causes this and there is no devtoolset-6 at http://mirror.as29550.net/mirror.centos.org/7.7.1908/sclo/x86_64/rh/ anymore.
Why is gcc-6 rather than 7 necessary?

Migrate away from Jabba JDK/Java version manager

https://github.com/shyiko/jabba is basically EOL/dead/unmaintained and currently there is no easy way to get particular JVM point releases installed from Adoptium or similar.

In lieu of better options possibly we should migrate to asdf, allowing us to later consolidate away from rvm and other version managers.
