* | configure runtime without storebaude2019-07-01
|/ | | | | | | | | some podman commands do not require the use of a container/image store. in those cases, it is more effecient to not open the store, because that results in having to also close the store which can be costly when the system is under heavy write I/O loads.

* | rootless: enable linger if /run/user/UID not existsGiuseppe Scrivano2019-06-27
| | | | | | | | | | | | | | | | | | | | | | | | | | at least on Fedora 30 it creates the /run/user/UID directory for the user logged in via ssh. This needs to be done very early so that every other check when we create the default configuration file will point to the correct location.

* | runtime: do not attempt to use global conf fileGiuseppe Scrivano2019-06-27
| | | | | | | | | | | | | | | | | | we had a regression where the rootless user tried to use the global configuration file. We should not try to use the global configuration when running in rootless but only cherry-pick some settings from there when creating the file for the first time.

| * remove libpod from mainbaude2019-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | the compilation demands of having libpod in main is a burden for the remote client compilations. to combat this, we should move the use of libpod structs, vars, constants, and functions into the adapter code where it will only be compiled by the local client. this should result in cleaner code organization and smaller binaries. it should also help if we ever need to compile the remote client on non-Linux operating systems natively (not cross-compiled).

| * Correctly identify the defaults for cgroup-managerDaniel J Walsh2019-06-15
| | | | | | | | | | | | | | | | | | | | | | Currently we report cgroupmanager default as systemd, even if the user modified the libpod.conf. Also cgroupmanager does not work in rootless mode. This PR correctly identifies the default cgroup manager or reports it is not supported. Also add homeDir to correctly get the homedir if the $HOME is not set. Will attempt to get Homedir out of /etc/passwd. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>

* | Make a missing OCI runtime nonfatalMatthew Heon2019-06-19
| | | | | | | | | | | | | | | | | | | | We may want to ship configurations including more than one runtime configuration - for example, crun and runc and kata, all configured. However, we don't want to make these extra runtimes hard requirements, so let's not fatally error when we can't find their executables. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* | Begin adding support for multiple OCI runtimesMatthew Heon2019-06-19
|/ | | | | | | | | | | | | Allow Podman containers to request to use a specific OCI runtime if multiple runtimes are configured. This is the first step to properly supporting containers in a multi-runtime environment. The biggest changes are that all OCI runtimes are now initialized when Podman creates its runtime, and containers now use the runtime requested in their configuration (instead of always the default runtime).

* Improve DESTDIR/PREFIX/ETCDIR handlingLawrence Chan2019-06-14
| | | | | | | | | | | - PREFIX is now passed saved in the binary at build-time so that default paths match installation paths. - ETCDIR is also overridable in a similar way. - DESTDIR is now applied on top of PREFIX for install/uninstall steps. Previously, a DESTDIR=/foo PREFIX=/bar make would install into /bar, rather than /foo/bar. Signed-off-by: Lawrence Chan <element103@gmail.com>

* rootless: use a pause processGiuseppe Scrivano2019-05-17
| | | | | | | | | | | | | | | | | use a pause process to keep the user and mount namespace alive. The pause process is created immediately on reload, and all successive Podman processes will refer to it for joining the user&mount namespace. This solves all the race conditions we had on joining the correct namespaces using the conmon processes. As a fallback if the join fails for any reason (e.g. the pause process was killed), then we try to join the running containers as we were doing before.

| | | | | | | | | | | it is useful to migrate existing containers to a new version of podman.

* rootless: fix segfault on refresh if there are containersGiuseppe Scrivano2019-04-10
| | | | | | | | | create immediately a namespace if we need a refresh. This is necessary to access the rootless storage. Closes: https://github.com/containers/libpod/issues/2894 Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>
* rootless: use a single user namespaceGiuseppe Scrivano2019-04-01
| | | | | | | | | | | | | | | | | | | | | simplify the rootless implementation to use a single user namespace for all the running containers. This makes the rootless implementation behave more like root Podman, where each container is created in the host environment. There are multiple advantages to it: 1) much simpler implementation as there is only one namespace to join. 2) we can join namespaces owned by different containers. 3) commands like ps won't be limited to what container they can access as previously we either had access to the storage from a new namespace or access to /proc when running from the host. 4) rootless varlink works. 5) there are only two ways to enter in a namespace, either by creating a new one if no containers are running or joining the existing one from any container. Containers created by older Podman versions must be restarted. Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>

* Remove ulele/deepcopier in favor of JSON deep copyMatthew Heon2019-03-27
| | | | | | | | | | | | | We have a very high performance JSON library that doesn't need to perform code generation. Let's use it instead of our questionably performant, reflection-dependent deep copy library. Most changes because some functions can now return errors. Also converts cmd/podman to use jsoniter, instead of pkg/json, for increased performance. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* utils: split generation and writing of storage.confGiuseppe Scrivano2019-03-17
| | | | | | | | | | | | | split the generation for the default storage.conf and when we write it if not existing for a rootless user. This is necessary because during the startup we might be overriding the default configuration through --storage-driver and --storage-opt, that would not be written down to the storage.conf file we generated.
