This does a major refactor on the compose.go functions as well as brings
in a new era of v3 support to Kompose.
Similar to how we utilize libcompose, we utilize docker/cli's "stack
deploy" code which has a built-in v3 parser. We convert the parsed
structure to our own and then convert it to Kubernetes/OpenShift
artifacts.
solve #610
convert service.pid to Pod.Spec.HostPid
set Pod.Spec.HostPid to true if service.pid ="host", to false otherwise
update conversion.md on support for the key
Kubernetes container names must match the regex [a-z0-9]([-a-z0-9]*[a-z0-9])?
This excludes underscores, which is common in container names in compose.
now args provided under build in docker-compose file can be available in buildconfig.
it solves #406
Added unit test and functional test
solves #445
Separated key:"value" pairs by spaces
This commit Add support for cap_add & cap_drop which maps to
Pod.Spec.Container.SecurityContext.Capabilities.Add/Drop
Added unit tests for ConfigCapabilities function
Updated conversion.md on support for these keys
If we have a docker-file with root level volumes and we do a kompose up
using that docker-file, libcompose will add an additional _ followed by
the current directory name. Since kubernetes doesn't allow _ in the
objects created so kompose up will fail to deploy it. As a solution we
replace _ to - and we can then deploy it successfully.
Resolves#272 and #267
As there is no direct mapping of `cpushares` and `cpuset` to kubernetes,
it should not be read and should be moved to unsupported keys.
Now we can provide service name with "_" in docker-compose files and they will by converted as "-" in the generated artifacts by kompose eg, if the service name in docker-compose file is "foo_bar" then it will be converted into "foo-bar" in the generated artifacts
Fixes#486
This commit will add `dockerfilepath` key under Dockerstratergy in buildconfig.
dockerfilepath allow us to use dockerfiles which are named different than `Dockerfile` which are placed in context directory.
for example, for a docker-compose file:
```
version: "2"
services:
foo:
build:
context: "./build"
dockerfile: "Dockerfile-alternate"
command: "sleep 3600"
```
Resulting buildconfig will be:
```
apiVersion: v1
kind: BuildConfig
...
...
strategy:
dockerStrategy:
dockerfilePath: Dockerfile-alternate
type: Docker
...
...
```
fixes#436
This commit will add support for tmpfs, configEmptyVolumeSource
function is being modified as it have to work in two ways now.
(For emptyvols and tmpfs)
Added unit test for tmpfs too.
This commit refactors the code to remove more or less
all occurences of logrus.Fatalf() from the code under
pkg/ except for app.go where all the errors are being
handled currently.
This is being done since random logrus.Fatalf() calls
all around the code was making handling the errors,
unit testing and troubleshooting a bit more painful.
logrus.Fatalf() calls are either replaced by
return errors.New("new error")
or
return errors.Wrap(err, "annonate error")
calls, and the function signatures are accordingly
changed to accomodate the new return values.
The unit tests which previously used to check
if logrus.Fatalf() calls worked fine have also
been fixed to only check for errors now.
Fixes#416
kubernetes or openshift does not allow underscores in the object
names, while docker-compose does, in this commit the code has been
added to convert underscores to hypens.
In compoese.go while iterating on the ServiceConfig objects first
it's keys were pulled and then data was pulled separately which
can be done in one step by iterating on the dictionary.
This adds support for supplying for example:
"127.0.0.1:80:80/tcp" to docker-compose.yaml and converting it to it's
corresponding Kubernetes / OpenShift hostIP.
This commit also refactors the loadPorts function of compose.go
Closes https://github.com/kubernetes-incubator/kompose/issues/335
Due to changes to libcompose, NetworkConfigs now returns a default
network regardless if one has been provided or not.
An if statement is added that will debug output and ignore the default
network provided that it's the only network available.
This adds supports for stdin_open: bool and
tty: bool support for kubernetes and openshift
providers in kompose. This maps to the
template.Spec.Containers[0].Stdin and
template.Spec.Containers[0].TTY in Kubernets
world.
Also, added tests.
Fixes#344
Implements a kompose specific docker compose label "kompose.service.expose" which can be used to expose the specified services externally. The accepted values are of type string.
If the value is set to "true", the provider sets the endpoint automatically, and for any other value, the value is set as the hostname. If multiple ports are defined in a service, the first one is chosen to be the exposed.
Unit tests, functional tests, glide updates and docs have also been added in this commit for the related feature.
Moved label handling code from Transformer to loader,
to make it generic to handle creating service types.
Added new attribute to ServiceConfig which gets populated
in loader.
Fixes#273
