Not possible to pass arguments when doing docker run #1448
Description
We're building an image like this:
BUILD:
filegroup(
name = "entrypoint",
srcs = [
"entrypoint.sh",
],
)
pkg_tar(
name = "entrypoint_tar",
srcs = [
":entrypoint",
],
mode = "0755",
package_dir = "app"
)
container_image(
name = "docker",
base = "@google-cloud-sdk//image",
entrypoint = "/app/entrypoint.sh",
tars = [
":entrypoint_tar",
],
)
entrypoint.sh:
#!/usr/bin/env bash
set -ex
... some auth
bq "$@"
When running this locally with docker run bazel/task-images/bigquery:docker --help we see that the arguments are not passed to the entrypoint script:
$ docker run bazel/task-images/bigquery:docker --help
+ bq
If skip instead run by specifying the entrypoint like docker run --entrypoint /app/entrypoint.sh bazel/task-images/bigquery:docker --help we see that the arguments are passed:
$ docker run --entrypoint /app/entrypoint.sh bazel/task-images/bigquery:docker --help
+ bq --help
Not sure if this is an intended behaviour or not (and also not sure it should go here), but could not find any info when looking around.
