From ff5e2898041230978cef9af37dd87c09b07a77e8 Mon Sep 17 00:00:00 2001 From: Markus Wolf Date: Wed, 12 Oct 2022 18:30:56 +0200 Subject: [PATCH] test: add test for networking setup in act (#1375) * test: add test for networking setup in act This test makes sure that the hostname inside of act is resolvable. * fix: only merge existing container options When merging parsed container options without options being set in a job, the default docker options are returned and will override the expected defaults by act (e.g. network mode). This is a first attempt to mitigate this behavior and only merge settings if something was requested on a job. * refactor: split config merging into own function Co-authored-by: mergify[bot] <37929162+mergify[bot]@users.noreply.github.com> --- pkg/container/docker_run.go | 78 +++++++++++++++---------- pkg/runner/runner_test.go | 1 + pkg/runner/testdata/networking/push.yml | 14 +++++ 3 files changed, 63 insertions(+), 30 deletions(-) create mode 100644 pkg/runner/testdata/networking/push.yml diff --git a/pkg/container/docker_run.go b/pkg/container/docker_run.go index 79a44d18..b935166c 100644 --- a/pkg/container/docker_run.go +++ b/pkg/container/docker_run.go @@ -374,6 +374,52 @@ func (cr *containerReference) remove() common.Executor { } } +func (cr *containerReference) mergeContainerConfigs(ctx context.Context, config *container.Config, hostConfig *container.HostConfig) (*container.Config, *container.HostConfig, error) { + logger := common.Logger(ctx) + input := cr.input + + if input.Options == "" { + return config, hostConfig, nil + } + + // parse configuration from CLI container.options + flags := pflag.NewFlagSet("container_flags", pflag.ContinueOnError) + copts := addFlags(flags) + + optionsArgs, err := shellquote.Split(input.Options) + if err != nil { + return nil, nil, fmt.Errorf("Cannot split container options: '%s': '%w'", input.Options, err) + } + + err = flags.Parse(optionsArgs) + if err != nil { + return nil, nil, fmt.Errorf("Cannot parse container options: '%s': '%w'", input.Options, err) + } + + containerConfig, err := parse(flags, copts, "") + if err != nil { + return nil, nil, fmt.Errorf("Cannot process container options: '%s': '%w'", input.Options, err) + } + + logger.Debugf("Custom container.Config from options ==> %+v", containerConfig.Config) + + err = mergo.Merge(config, containerConfig.Config, mergo.WithOverride) + if err != nil { + return nil, nil, fmt.Errorf("Cannot merge container.Config options: '%s': '%w'", input.Options, err) + } + logger.Debugf("Merged container.Config ==> %+v", config) + + logger.Debugf("Custom container.HostConfig from options ==> %+v", containerConfig.HostConfig) + + err = mergo.Merge(hostConfig, containerConfig.HostConfig, mergo.WithOverride) + if err != nil { + return nil, nil, fmt.Errorf("Cannot merge container.HostConfig options: '%s': '%w'", input.Options, err) + } + logger.Debugf("Merged container.HostConfig ==> %+v", hostConfig) + + return config, hostConfig, nil +} + func (cr *containerReference) create(capAdd []string, capDrop []string) common.Executor { return func(ctx context.Context) error { if cr.id != "" { @@ -383,25 +429,6 @@ func (cr *containerReference) create(capAdd []string, capDrop []string) common.E isTerminal := term.IsTerminal(int(os.Stdout.Fd())) input := cr.input -
