People around the world are waking up each day grateful they don't have to deal with the side effects of prescription drugs. They are starting to make the right decision when it comes to treating their own illnesses and pains. Some of the best CBD gummy bears in the world are the Caramel Chocolate and Caramel Apple flavors. Both of these flavors offer users unique health benefits when it comes to losing weight. The Caramel Chocolate flavor is a uni-sweet, semi-sweet, dark chocolate that offers up to sixty percent of the recommended daily allowance of theobromine. This sweetener is a natural stimulant that can reduce headaches, improve mood, and aid in weight loss. Some people take gummy bears that contain ephedra to get high as well. They are taking a harmful substance in hopes of beating their addiction to caffeine by mixing it with a healthy product. This is not a good idea and can lead to dangerous side effects. The Caramel Apple product offers up to two grams of theobromine per every single serving. Many people like this because it tastes so great, but some people don't enjoy the taste at all. These products also contain a plethora of other benefits and are the best CBD gummies out there. You can experience all of the benefits of gummies without getting a buzz, without becoming addicted, without increasing your heart rate, and without feeling any jitters or anxiety. If you're trying to get healthy, reduce your stress level, and feel more energized, try the Caramel Apple! They're great all around snacks and delicious treats. If you're looking for a healthy alternative to sugar and carbohydrates, the Caramel Apple is one of the best ways to do it. There are many different CBD products out there that are great to help people sleep and curb their anxiety levels. Gummy bears, tablets, and even energy drinks are just a small part of what you can get out of these products. Try shopping for these gummy bears today! If you love chocolate and want to take a healthy, natural approach to curb your hunger, you'll love the Caramel Apple. With its high-quality gummy bear base, it provides a satisfying crunch while supplying high-quality, sustained energy throughout the day. This delicious gummy bear is made with Simpler Raw High-Residue Chocolate from New Zealand. Other popular brands include; Ganocafe, Strudel's Goji Berry Power, and My-Cap Ultra. These are just three of the best brands of CBD gummies available, and all offer high-quality gummy bear options for anyone looking to benefit from a healthy diet and high-quality exercise.

Writting a Podman client using the OpenAPI specifications
by Tristan Cacqueray 08 Mar '21

08 Mar '21

Hi folks, I've been writting a client from scratch using the OpenAPI specifications, here is some information others might find useful. The specification contains incomplete or incorrect definitions. Most of the definitions are missing the required field list, for example, the SpecGenerator does not indicate that the image name is required. And here is an example of an incorrect definition: https://github.com/containers/podman/issues/9578 The definitions location is not always consistent. Most of them are in the top level `definitions` map, but some are defined differently. For example: - ExecConfig is specified in the path body, instead of using a schema reference. - LibpodImagesPullResponse is defined in the `responses` map, but it just references another definition, causing an extra indirection. Some endpoints need custom logic, for example: - container/attach upgrades the connection to a tcp stream using a binary format (see util.go makeHTTPAttachHeader). - container/logs returns a binary chunked stream. - images/pull returns a raw list of json objects. - exec/start returns a raw integer. API versioning does not seem to be implemented, and the current version number is unclear. Thus, generating the client code using swagger-codegen does not work well. Instead, I wrote a custom script to process and fix the definitions one endpoint at a time. I was able to cover a significant amount of the endpoints and you can see a preview of the client here: https://docs.softwarefactory-project.io/podman-haskell/ Regards, -Tristan

Included at the top of that page is a link to the BlueJeans Recording. Our next meeting is Tuesday April 6, 2021 at 8:00 p.m. Eastern (UTC-4).

Also one last reminder for the Container Plumbing Conference that starts tomorrow at 9:30 a.m. Eastern (UTC-5) and then again on Wednesday at the same time. We had issues with the registration showing "full" last week, but that has since been fixed. If you've not registered, I hope you do! https://containerplumbing.org/ Best Wishes, t

Macvlan
by Rusty Sapper 03 Mar '21

03 Mar '21

I’m having trouble setting up a macvlan. I created my config under /etc/cni/net.d and can successfully start my continater with the macvlan network. However, when I exec into the container, it has no network access to anything except itself. I apologize, I'm new to podman. I need to be able to ssh into other hosts(jenkins nodes) to run tests. I am unable to use the host network due to other requirements. Any help would be appreciated. here is my macvlan config: { "cniVersion": "0.4.0", "name": "testmac1", "plugins": [ { "type": "macvlan", "master": "eno1np0", "ipam": { "type": "host-local", "routes": [ { "dst": "0.0.0.0/0" } ], "ranges": [ [ { "subnet": "10.89.0.0/24", "gateway": "10.89.0.1" } ] ] } }, { "type": "portmap", "capabilities": { "portMappings": true } } ] } ~

March 2, 2021 Podman Community Meeting Video Recording
by Tom Sweeney 02 Mar '21

02 Mar '21

Hi All, We held the March Podman Community Meeting earlier today and in case you missed it, the video is up for replay at: https://bluejeans.com/s/w9MNLQGTmf3 It was a jam packed agenda with some really great demos on krunvm and tent. I'm working on the notes from the meeting now and will add a link to the video there once they are posted on podman.io. I'll also include approximate start times inside the notes if you want to peruse that way later. However, I may not get those posted for a few days, so thought I'd send out this video link. Thanks to all who attended and hope to see some new faces at the Tuesday April 6, 2021 meeting as that will be held at 8:00 p.m. Eastern (UTC-4) to try and make it a bit more friendly to the folks in the Asia regions. t

Pushing image tagged with multiple tags to remote repo with the same digest
by Marcin Zajączkowski 02 Mar '21

02 Mar '21

Hi. I might miss something obvious - I don't have deep knowledge about containers, however, trying to migrate my docker-in-docker image building CI job to buildah, I've encountered the following problem. My image should be tagged with its real version and in addition with a special marker tag (such as "devel" or "stable" or "latest"). It seems to be a common practice with images. While in docker, I could just call: > docker build -t "$CI_REGISTRY_IMAGE:$VERSION" -t "$CI_REGISTRY_IMAGE:$MARKER_TAG" > docker push $CI_REGISTRY_IMAGE" with buildah, it is more problematic as I cannot use multiple tags on push (--all-tags switch has been also abandoned). I tried: > buildah bud -t "$CI_REGISTRY_IMAGE:$VERSION" -t "$CI_REGISTRY_IMAGE:$MARKET_TAG" > buildah push "$CI_REGISTRY_IMAGE:$VERSION" "$CI_REGISTRY_IMAGE:$VERSION" > buildah push "$CI_REGISTRY_IMAGE:$MARKET_TAG" "$CI_REGISTRY_IMAGE:$MARKET_TAG" but while "buildah images --digests" shows the same digest for those two tags, in the remote repository (GitLab CI container repository) these tags have two different digests (also both differ from the local one). I suspect there could be something changed in the manifest. Q. How can I have one image (with one digests) tagged multiple times in a container repository using buildah? buildah version 1.18.0 (image-spec 1.0.1-dev, runtime-spec 1.0.2-dev) on Fedora 33. Marcin P.S. I've seen https://github.com/containers/buildah/issues/2034, but I don't know if it is related.
