mercer/pipeline


• vagrant up
• visit [virtualbox]:8080 and configure a build job
• DOCKER_HOST is set to the docker as a service container
• REGISTRY_HOST is set to the registry as a service container

• commit (compile, package, test, automated code review, [reports], publish, marked)
• acceptance
• uat
• performance
• production

• i'd like to clearly see all steps a build goes through
• i'd like to have good monitoring of my containers
• i'd like to have good management of statefull containers

• i should commit to registry from gradle, not from jenkins
• Vagrant
• jenkins with java 1.8
• clean up gradle configuration
• ONBUILD trigger to pack a deployable artifact with a container (tomcat)
• add javadoc task call
• remove expose ports duplication from own Dockerfile
• cleanup all the mixes of pipeline config and env config, and all other config; remove hardcoded credentials
• have config pass guest os appliance urls and not component urls (fetch ports/host os ip)
• use artifactory as proxy/mirroring
• mirroring with docker registry
• shipyard?
• start mysql and tomcat in delivered container?
• DOCKER_HOST in jenkins container should not be hardcoded in the Dockerfile
• what if i'm not in boot2docker, is it ok for jenkins to be reliant on an outside docker provider?
• remove war file from artifactory (when doing a FROM, a hook is triggered for which you need to specify a war file)
• enable authentication to the registry (fixes "Invalid registry endpoint" errors)
• add dockerfile link in hub for repos
• build total time?
• diagnostics on all containers?
• fix publish to unsecure registry
• start one build artifact container from registry by hand
• start several containers from registry by hand
• add war file to build artifact container
• build the deployable artifact
• expose the appliance's ports to localhost
• docker artifactory
• docker registry appliance
• fetch build number to version strategy
• fix boot2docker os system time
• have sonar run on all
• remove ports, if possible
• make acceptance build job
• make acceptance job downstream of commit
• research gradle acceptance tasks
• create an (empty) acceptance gradle task
• fetch any war from artifactory
• fetch the correct war from artifactory
• continue to fetch the correct war after artifactoru container is recreated

• I have a friendly entry point to services (ports are random)

• restore state
• start container
• state backuped from time to time, serve clients
• container stopped
• state backedup or archived
• if service died, logs and such should be saved for forensics purposes
• container erased

• docker: started on 192.168.59.103:8080; how do I expose it on lan? on internet?
• docker: how do i get it on a Digitalocean instance? vagrant?
• docker: how to save/provision jenkins settings, plugins, build pipelines?
• docker: linked containers dependencies when starting? can a container start it's dependencies, wait for them to be completely started, then start itself?
• how to deliver artifacts in conjunction with docker? is an artifact (war) repository still needed?
• should a container be stateless? where should all state go? db, logs, all kinds of bits and bytes
• should we or shouldn't we use latest tags? versions should be under control, no?
• when giving passwords as parameters to containers, ok in clear? where should they come from?
• when starting a container, random ports --> localhost or not?
• how to debug boot2docker?
• how to debug containers that fail to start?
• postgres?
• add build info together with artifact?
• extend Dockerfiles to install plugins on jenkins and sonar?
• jenkins jobs to git?
• how much space do container instances occupy? what about container snapshots?
• sidekick container specialized on backup?
• multi-container dockerfile?
• when starting all containers, how to start dependencies first?
• if upstream commit build has number x, downstream acceptance build has number y, is y relevant?
• before commiting an container increment, shouldn't it be started to verify that it works (smoke tests)

• jenkins
• sonar-mysql
• sonar; default user and password for mysql is sonar:123qwe

• what if we store in artifact repository only the deployable artifacts?

• https://issues.gradle.org/browse/GRADLE-3062 -> upgrade to gradlew 2.2+
• VOLUME didn't work in Dockerfile -> you're not supposed to do it like that, state is maneged outside Dockerfile
• when sharing a volume, owner is set to root of the container; moby/moby#3124 and others; and https://groups.google.com/forum/#!topic/docker-user/cVov44ZFg_c and moby/moby#5189 -> only solution so far is to run the container with root :/
• local insecure private docker registry: see moby/moby#8887 (comment) and http://wanderingquandaries.blogspot.ro/2014/11/setting-up-insecure-docker-registry.html
• sometimes the registry container fails to start with "2014-11-09 23:49:15 [17] [ERROR] Exception in worker process:"
• after adding tags for a deployable docker container, now build tags are too long https://i.imgur.com/uIbroci.png
• ubuntu service does not start at container start time (jenkins container with apache2)
