bug

Affected Product Version: Ballerina version 0.982.0

OS, DB, other environment details and versions: macOS High Sierra 10.13.6

Steps to reproduce:

1. Clone this repo -
2. Run these commands :

$ ballerina pull wso2/twitter
$ ballerina build hello_service.bal
$ docker run -d -p 9090:9090 registry.hub.docker.com/karuppiah7890/ballerina_hello_world:v0.0.1

And you should be able to see the issue using these commands :

$ docker ps -a

I tried to debug it. Here are some commands that I ran and their outputs :

$ docker run -d -p 9090:9090 registry.hub.docker.com/karuppiah7890/ballerina_hello_world:v0.0.1

Looking at all this, I feel that the args is wrong in the start command of the container - basically the ballerina run command is wrong.

        "Args": [
            "-c",
            "ballerina run hello_service.balx --config ./home/ballerina/conf/twitter.toml"
        ],

The --config flag and it's values should come before the hello_service.balx file, from what I see in ballerina help run. @anuruddhal can you please check this and confirm ? If this is the bug, I can raise a PR 😄 I might need some help with the tests though

Hi All,

We are using the following command in generated Dockerfile and docker images.

CMD java -jar hello.jar --b7a.config.file=${CONFIG_FILE}

I would like to propose a new annotation @docker:CMD that allowed the user to alter the default CMD line. Some cases use have to use custom CMD, eg write logs to deferent mount paths rather writing to console out.

eg. @docker:CMD("CMD java -jar ${APP} --b7a.config.file=${CONFIG_FILE} > /var/log/ballerina.log 2>&1")

For the moment this can't be done unless manually edit the Dockerfile and regenerate the image. This is an optional annotation and this will work handy in several use-cases.

username:"username",
password:"password"
}

Addition to above, I am proposing following option

• docker auth string

Propose annotation
@docker:configuration {
push:true,
registry:"index.docker.io/username",
name:"helloworld-push",
tag:"v2.0.0",
dockerAuth:"auth string"
}

auth string can be find in ~/.docker/.dockercfg or ~/.docker/config.json

Description:
Working on CI/CD flow with ballerina and currently trying to build via the docker container.
Example:
docker run -v $(pwd):/home/ballerina --rm ballerina/ballerina-platform:0.981.1 ballerina build sims.bal

sims.bal builds fine when running via mac ballerina build.

When running via docker container I get the following output:

docker run -v $(pwd):/home/ballerina --rm ballerina/ballerina-platform:0.981.1 ballerina build sims.bal
Compiling source
    sims.bal

@docker:CopyFiles should be supported in main function

We should have a way to pass env key: values to the docker container

Maybe we can use the following syntax

@docker:Config {
env: [
{ env-variable-name: "value"},
{ secret: "$env{PASSWORD}"}
]
}

Description:
When I put my docker annotation at the top of my .bal file, I often get an error because the first code block is an endpoint. Since the docker annotation really applies to the .bal, maybe we could allow binding to both services and endpoints.

Current we are connecting to docker daemon by using /var/run/docker.sock. This is work if we install docker in local machine or if you used docker for mac.

If we want to use remote docker host to create docker images, we should allow to connect. Example if we use minikube we need to connect via socket.

Propose annotation to support this
@docker:configuration{dockerHost:tcp://IP:PORT} .
Default value should be tcp://127.0.0.1:2375

Description:
ballerina build [module-name] returns an error:

error [docker plugin]: module [ballerinaplayground/playground:0.1.0] unable to connect to server:   org.apache.http.client.ClientProtocolException

Affected Product Version:
Ballerina 1.0.4
OS, DB, other environment details and versions:
Windows 10, Docker Desktop 2.1.0.5

Steps to reproduce:

• Create a project with modules and add docker to it:

@docker:Expose {}
listener http:Listener listenerName = new(9090);

@docker:Config { name: "dockerName", tag: "v1.0", dockerHost: "localhost"}  // Expose Docker daemon to localhost for this to work
service serviceName on listenerName {

• Run ballerina build [module-name]

Note: If docker is used for a single file (Ballerina build file.bal) everything works fine

In the HTTP calls that are done by Docker clients to the Docker daemon, we can optionally set the Docker API version with the requests. This is sometimes required, to make sure we bind our actions with a specific API version. Also, some Docker daemon implementations require users to set the API version, e.g. GitHub Actions.

So due to this, we need to way to provide the Docker API version to be used by the client. I suggest using an environment variable to set it, when the Ballerina build is happening. The environment variable for this can be "DOCKER_API_VERSION".
