* bump go module to v3Valentin Rothberg2021-02-22
| | | | | | | | | We missed bumping the go module, so let's do it now :) * Automated go code with github.com/sirkon/go-imports-rename * Manually via `vgrep podman/v2` the rest Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* Enable golint linterPaul Holzinger2021-02-11
| | | | | | | | Use the golint linter and fix the reported problems. [NO TESTS NEEDED] Signed-off-by: Paul Holzinger <paul.holzinger@web.de>
* Stop excessive wrapping of errorsDaniel J Walsh2020-10-30
| | | | | | | | | | | | Most of the builtin golang functions like os.Stat and os.Open report errors including the file system object path. We should not wrap these errors and put the file path in a second time, causing stuttering of errors when they get presented to the user. This patch tries to cleanup a bunch of these errors.

* Do not print an error message on non-0 exec exit codeMatthew Heon2020-07-21
| | | | | | | | | | | This was added with an earlier exec rework, and honestly is very confusing. Podman is printing an error message, but the error had nothing to do with Podman; it was the executable we ran inside the container that errored, and per `podman run` convention we should set the Podman exit code to the process's exit code and print no error.

* move go module to v2Valentin Rothberg2020-07-06
| | | | | | | | | | | | | | | With the advent of Podman 2.0.0 we crossed the magical barrier of go modules. While we were able to continue importing all packages inside of the project, the project could not be vendored anymore from the outside. Move the go module to new major version and change all imports to `github.com/containers/libpod/v2`. The renaming of the imports was done via `gomove` [1].

* separate healthcheck and container log pathsBrent Baude2020-04-27
| | | | | | | | instead of using the container log path to derive where to put the healthchecks, we now put them into the rundir to avoid collision of health check log files when the log path is set by user. Fixes: #5915 Signed-off-by: Brent Baude <bbaude@redhat.com>
* v2podman attach and execBrent Baude2020-04-05
| | | | | | | | add the ability to attach to a running container. the tunnel side of this is not enabled yet as we have work on the endpoints and plumbing to do yet. add the ability to exec a command in a running container. the tunnel side is also being deferred for same reason.

* Add structure for new exec session tracking to DBMatthew Heon2020-03-18
| | | | | | | | | | | | | | | | | | | | | | | As part of the rework of exec sessions, we need to address them independently of containers. In the new API, we need to be able to fetch them by their ID, regardless of what container they are associated with. Unfortunately, our existing exec sessions are tied to individual containers; there's no way to tell what container a session belongs to and retrieve it without getting every exec session for every container. This adds a pointer to the container an exec session is associated with to the database. The sessions themselves are still stored in the container. Exec-related APIs have been restructured to work with the new database representation. The originally monolithic API has been split into a number of smaller calls to allow more fine-grained control of lifecycle. Support for legacy exec sessions has been retained, but in a deprecated fashion; we should remove this in a few releases. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

* Switch to bufio Reader for exec streamsPeter Hunt2019-10-31
| | | | | | | | There were many situations that made exec act funky with input. pipes didn't work as expected, as well as sending input before the shell opened. Thinking about it, it seemed as though the issues were because of how os.Stdin buffers (it doesn't). Dropping this input had some weird consequences. Instead, read from os.Stdin as bufio.Reader, allowing the input to buffer before passing it to the container. Signed-off-by: Peter Hunt <pehunt@redhat.com>
* Move OCI runtime implementation behind an interfaceMatthew Heon2019-10-10
| | | | | | | | | | | | For future work, we need multiple implementations of the OCI runtime, not just a Conmon-wrapped runtime matching the runc CLI. As part of this, do some refactoring on the interface for exec (move to a struct, not a massive list of arguments). Also, add 'all' support to Kill and Stop (supported by runc and used a bit internally for removing containers). Signed-off-by: Matthew Heon <matthew.heon@pm.me>

* healthcheck: reject empty commandsStefan Becker2019-07-16

* healthcheck: improve command list parserStefan Becker2019-07-16
| | | | | | | | | | | - remove duplicate check, already called in HealthCheck() - reject zero-length command list and empty command string as errorneous - support all Docker command list keywords: NONE, CMD or CMD-SHELL - use Docker default "/bin/sh -c" for CMD-SHELL Fixes #3507 Signed-off-by: Stefan Becker <chemobejk@gmail.com>

* Begin to break up pkg/inspectMatthew Heon2019-06-03
| | | | | | | | | | Let's put inspect structs where they're actually being used. We originally made pkg/inspect to solve circular import issues. There are no more circular import issues.

* podman health check phase3baude2019-03-22
| | | | | | | | | | | | | | | | podman will not start a transient service and timer for healthchecks. this handles the tracking of the timing for health checks. added the 'started' status which represents the time that a container is in its start-period. the systemd timing can be disabled with an env variable of DISABLE_HC_SYSTEMD="true". added filter for ps where --filter health=[starting, healthy, unhealthy] can now be used.

* healtcheck phase 2baude2019-03-12
| | | | | | | | | | | | | | | | | | | | | | | | | | integration of healthcheck into create and run as well as inspect. healthcheck enhancements are as follows: * add the following options to create|run so that non-docker images can define healthchecks at the container level. * --healthcheck-command * --healthcheck-retries * --healthcheck-interval * --healthcheck-start-period * podman create|run --healthcheck-command=none disables healthcheck as described by an image. * the healthcheck itself and the healthcheck "history" can now be observed in podman inspect * added the wiring for healthcheck history which logs the health history of the container, the current failed streak attempts, and log entries for the last five attempts which themselves have start and stop times, result, and a 500 character truncated (if needed) log of stderr/stdout. The timings themselves are not implemented in this PR but will be in future enablement (i.e. next). Signed-off-by: baude <bbaude@redhat.com>
* podman healthcheck run (phase 1)baude2019-03-05
Add the ability to manually run a container's healthcheck command. This is only the first phase of implementing the healthcheck. Subsequent pull requests will deal with the exposing the results and history of healthchecks as well as the scheduling. Signed-off-by: baude <bbaude@redhat.com>
