This PR adds support for HealthCheck, being able to supply, for example:
```yaml
version: "3"
services:
redis:
image: redis
healthcheck:
test: echo "hello world"
interval: 10s
timeout: 1s
retries: 5
```
Which is then converted to:
```yaml
spec:
containers:
- image: redis
livenessProbe:
exec:
command:
- echo "hello world"
failureThreshold: 5
periodSeconds: 10
timeoutSeconds: 1
name: redis
resources: {}
restartPolicy: Always
```
At the moment, this only supports livenessProbe, with support for readinessProbe in the future.
Adds support for deploy: mode.
For example:
```yaml
version: "3"
services:
foo:
deploy:
resources:
mode: global
replicas: 6
image: redis
```
Will only generate replicas: 1 in Kubernetes pods as "global" limits
replicas to only one.
This command will add `kompose command` used to generate artifacts as well as `kompose version`,
for ex,
```
metadata:
annotations:
kompose.cmd: kompose convert -f /home/snarwade --stdout
kompose.version: 1.0.0 (HEAD)
```
For functional test, Now each test has template like,
```
"annotations": {
"kompose.cmd": "%CMD%",
"kompose.version": "%VERSION%"
```
Because, for every machine these values will be different.
Updated functional test with new annotations
In pkg/app/app.go, the function ValidateComposeFile() has an
unused parameter "cmd *cobra.Command".
This commit removes that parameter from the function and the
callers of the function.
This adds support for building and pushing docker containers
when you perform either `kompose convert` or `kompose up`.
Docker Compose files who have build parameters with their respective
image and build keys will automatically be both built and pushed.
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
Adds the provider name to the file output. For example:
```sh
INFO OpenShift file "frontend-service.yaml" created
INFO OpenShift file "redis-master-service.yaml" created
INFO OpenShift file "redis-slave-service.yaml" created
INFO OpenShift file "frontend-deploymentconfig.yaml" created
INFO OpenShift file "frontend-imagestream.yaml" created
INFO OpenShift file "redis-master-deploymentconfig.yaml" created
INFO OpenShift file "redis-master-imagestream.yaml" created
INFO OpenShift file "redis-slave-deploymentconfig.yaml" created
INFO OpenShift file "redis-slave-imagestream.yaml" created
```
For services with build and image keys DeploymentConfig respects tag from docker-compose image key.
But BuildConfig image tag was always set to 'latest'.
Result of this was that deployment wasn't trigired after successful build.
This fixes it by setting BuildConfig output image tag to the same tag that is used for DeploymentConfig (tag from docker-compose image 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
`k8s.io/kubernetes/pkg/api` is imported directly and once with the alias
import name `kapi` so remove the original import and keep the aliased with
`kapi` one and also replace the code bits which call it with `api` name.
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
fixes#445
This PR was partially fixed by docker/libcompose#450, which now gives consistent build context,
also it modifies the function getAbsBuildContext to create accurate build context, Unit test are being modified
according to new structure.
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.
Now we can deploy application in different namespaces using the "--namespace=<value>" flag with kompose up and kompose down. The --namepace flag will deploy the application in that particular "namespace" if exist."
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.
fixes#270
all errors in undeploy method(both kubernetes and openshift) are appended in a slice of errors,
and then it will be returned after successful deletion of all components.
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#270
all errors in undeploy method(both kubernetes and openshift) are appended in a slice of errors,
and then it will be returned after successful deletion of all components.
This PR uses the "SelectorFromSet()" function which takes alabel or
selector as an argument returns all the object that uses that label or
selector. Once we get the object that uses a particular label we can
further do the delete operation on them. This is similar to "kubectl
delete <object> --selector=<key>=<value>". Also the label has been
modified from service to io.kompose.service.
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 adds github.com/pkg/errors to glide.yaml followed
by glide and glide-vc commands. The github.com/pkg/errors
package is currently required mainly for the errors.Wrap()
and errors.New() methods, since this lets us to annotate the
errors while passing the error message up the call stack.
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
When volumes are specified in the Docker Compose
files, then in case of Kubernetes, Deployment's
Spec.Strategy.Type and in case of OpenShift,
DeploymentConfig's Spec.Strategy.Type are set to
"Recreate". This is a safer deployment strategy
when Volumes are getting used.
This commit also adds unit tests for Kubernetes
as well as OpenShift, and fixes the failing
functional tests (tests.sh) due to the change.
No functional tests have been added since
the functionality is already covered when the
volume mounts are being tested earlier in the
file.
This fixes#264
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.
