airship's Introduction

Airlift

Airlift is a framework for building REST services in Java.

This project is used as the foundation for distributed systems like Trino (formerly PrestoSQL).

Airlift pulls together stable, mature libraries from the Java ecosystem into a simple, light-weight package that lets you focus on getting things done and includes built-in support for configuration, metrics, logging, dependency injection, and much more, enabling you and your team to ship a production-quality web service in the shortest time possible.

Airlift takes the best-of-breed libraries from the Java ecosystem and glues them together based on years of experience in building high performance Java services without getting in your way and without forcing you into a large, proprietary framework.

airship's Issues

Config bundler doesn't push release tags

The config bundler when creating a release pushes the artifact up to nexus, but does not push the tag to git. This can cause problems if someone forgets to push the tags for the released config.

Is this expected behavior?

Config bundler NPE when missing server settings

An NPE occurs if the settings file doesn't have a <server> entry with a matching <id>. The result of settings.getServer(...) needs to be checked for null with an appropriate user error thrown.

Exception in thread "main" java.lang.NullPointerException
at io.airlift.airship.configbundler.Maven.makeRemoteRepository(Maven.java:102)

at io.airlift.airship.configbundler.SnapshotCommand.call(SnapshotCommand.java:21)
at io.airlift.airship.configbundler.ConfigBundler.main(ConfigBundler.java:31)

Additionally, the constructor for that class has the repository info parameters as @Nullable when they should not be. The validateRepositoryMetadata method should validate them as not null.

Git default HEAD not pointing to master causes inability to do a snapshot or release

If you have a repository that you clone who's HEAD points to a different branch than master (on initial clone) you can not do a release or snapshot until the master branch is checked out.

Theoretical reproduction:
$ git clone {git repo} foo
$ cd foo
$ git checkout config-branch
$ asconfig snapshot
Exception in thread "main" java.lang.NullPointerException
at io.airlift.airship.configbundler.Model.readMetadata(Model.java:60)

at io.airlift.airship.configbundler.SnapshotCommand.call(SnapshotCommand.java:21)
at io.airlift.airship.configbundler.ConfigBundler.main(ConfigBundler.java:31)

This problem goes away after you checkout the master branch.

Config bundler doesn't support encrypted nexus passwords

"coordinator ssh" doesn't work

Ssh command uses local username

The ssh command always uses the local username when connecting to a remote machine. This is generally never what's expected; especially in the case of AWS where all the machines have a single username.

An incomplete configuration can be created

I created a configuration bundle using asconfig that did not have a jvm.properties and I was allowed to create this bundle and discovered the issue when the server started up. Would be nice to be warned while creating the configuration that its insufficient.

Config bundler should add to local maven repo

Currently the config bundler doesn't push to the local maven repo making it difficult to install locally built software with local configs.

Command line tools need a version option

Nuff said.

Agent terminate doesn't function

Repro steps:

Create a new environment
Provision one or more agents
Run 'airship agent terminate' with the uuid of one of the agents
The above fails saying it can't find the agent.

install --all doesn't work

Performing an 'airship install --all' only tries to install the specified software on one server, not all available servers. Doing some packet sniffing it does seem like the Coordinator returns all of the existing servers, but the airship cli must not be handling them correctly.

I have tested this with 3 existing airship agents.

Steps that work for me to reproduce:

Build new environment
Make 3 agent servers
Try to do install --all

My airship cli server is a RHEL 6.x Linux box with the latest JDK from Oracle and I'm running as the root user.

Airship config bundler broken since 0.11

The config bundler is broken after 0.11, but worked in 0.10.

There are two issues; first you can not initialize a new config repo:

$ asconfig-0.12 init --groupId com.example.config --releasesRepository nexus --snapshotsRepository nexus --releasesRepositoryUri 'http://192.168.193.6:8082/nexus/content/repositories/releases' --snapshotsRepositoryUri 'http://192.168.193.6:8082/nexus/content/repositories/snapshots'

JNR issue at 93bc0bc97abb76d4930b97dccec40de9faef68f5 (Current HEAD)

First provisioned a coordinator; which worked correctly:

$ ./airship environment provision-aws --coordinator-config \
> com.example.config:airship-coordinator:1 \
> --instance-type t1.micro --security-group sec-group --ami ami-3e41d257 --key-pair airship-test \
> --repository http://example.com:8082/nexus/content/groups/public/ staging
Waiting for access key to register with AWS......done!

Second tried to provision some agents:

$ ./airship agent provision --agent-config @com.example.config:agent-aws-t1.micro:1 \
> --instance-type t1.micro --security-group sec-group --ami ami-3e41d257 \
> --key-pair airship-test --count 3

And get this:

Upgrading a coordinator clobbers aws-credentials.properties file

To repro:

Provision an aws environment
Ssh manually to the coordinator
"airship -e airship upgrade -b airship-coordinator @some-new-config:42"

At this point the aws-credentials.properties file has been deleted by the config upgrade and the coordinator both dies and is not recoverable.
